Designing Cisco Network Service Architectures (300-320) Exam Description: The Designing Cisco Network Service Architectures (ARCH )exam (300 -320 is a 75 minute assessment with 60 – 70 questions associated with the Cisco Certified Design Professional certification. This command requires a reload before taking effect. VXLAN is a widely used data-center interconnect (DCI) technology, and can be implemented using Arista vEOS or Cisco CSR1000v to seamlessly connect data-centers. Contiv is all open sourced. VNI - VXLAN Network Identifier (similar to a VLAN ID) Each VXLAN network identified by a unique VNI is an isolated logical network. The ACI architecture uses VXLAN headers. A New Cloud Network “Spline™” Is Born. Building DataCenter networks with VXLAN BGP-EVPN V3 BGP Route-ReflectorRR iBGP Peering* *eBGP supported without BGP Route-Reflector and look at the WHOLE. ACI doesn't support fragmentation (very sensitive, I know :-)) so because of the 50 bytes of overhead introduced by VXLAN (54 bytes if VLAN tag is used) the configuration of front panel ports on leaf that the servers connect to has the MTU = 9000 byte whereas the fabric uplink ports have the MTU = 9150; so, fair enough if we consider that. Kamal Kumar has 5 jobs listed on their profile. Other devices in this solution include the ConnectX® family of network interface cards, and LinkX® copper or fiber cabling. View Mitesh Kanjariya’s profile on LinkedIn, the world's largest professional community. VTEPs rely on data-plane learning or a control plane in order to determine the remote endpoint to VTEP mapping for traffic encapsulation. Each overlay network is called a VXLAN segment and is identified using a 24-bit VXLAN network identifier (VNI), which sup-. The primary physical difference between ACI and NSX is that NSX maintains the VTEPS as VMKernel ports that belong to the ESXi hosts that have virtual wires or virtual switches. Additionally, ACI alleviates the need for gateway servers by providing gateway, bridging, and routing functions for untagged, VLAN, VxLAN, and NVGRE on any port. Support the planning and implementation of ACI automation. Rather ACI is an entire SDN solution wrapped around the idea that IT applications are the most important thing in an organization. Cisco has provided a complete solution based on this VXLAN Overlay. Developing Cisco ACI modules Detailed guide on how to write your own Cisco ACI modules to. Yes, I am still talking about VXLAN, rather you folks are still talking about VXLAN, so I thought its worthwhile digging deeper into the topic since there is so much interest out there. VMware, Arista, and Cisco created the original VXLAN specification. Is that just because people aren't comfortable with BGP or are there specific use cases where ACI makes a big difference? I can believe that a massive software project like ACI is a hot mess, being from Cisco. One way is to use OpenFlow, an SDN standard often criticized for poor scalability. Symptom: Traffic with a UDP destination port of 8472 is dropped on ingress by the ACI fabric. - a packet going across the ACI fabric will be first encapsulated by NSX at the vSwitch with a VXLAN header for VM to VM connectivity. As the newest advance in the Cisco ACI methods to interconnect networks, Cisco ACI Multi-Site is an architectural approach for interconnecting and managing multiple sites, each serving as a single fabric and availability zone. The below diagram details a VXLAN fabric deployment. In this post, we’ll discuss this ACI engine (called the Application Policy Infrastructure Controller or APIC), as well as the direction that Cisco’s going from a perspective of programmability. VXLAN VLAN NVGRE VLAN VXLAN VLAN ESX Hyper-V KVM Hypervisor Management ACI Fabric APIC Security Admin Integrated hardware gateway for virtual and physical resources Multi-Hypervisor ready Physical Server ready Real Time Visibility Information Model across network-domains (DC, Enterprise, Service Provider). APICs are deployed as highly available clusters. As NSX gains broader adoption, we have heard many customer requests for guidance to help them run NSX on top of the latest Cisco infrastructure, UCS and Nexus 9000 series switches. The same naming convention for Pod, Multi-Pod, Multi-Fabric and Multi-Site has been elaborated for both VXLAN EVPN Standalone and ACI. This article provides a way to design and implement such a network security architecture using Border Gateway Protocol (BGP) + VXLAN tunnels along with VM-series firewall from Palo Alto Networks. By creating a new way to link networks and applications in a highly virtualized data center, Cisco ACI is considered as “a revolutionary re-thinking of how to provision and manage data center networks”. Cisco ACI supports VLAN, VXLAN, and network virtualization using generic routing encapsulation (NV-GRE), which can be combined and bridged together to create a logical network/domain as needed. Cisco Confidential 16 VXLAN VNID = 5789 VXLAN VNID = 11348 NVGRE VSID = 7456 Any to Any 802. The goal is to show students how to use the ACI in a live working environment, first starting with its fundamental operation, and then focusing on integration and migration scenarios. As a policy automation engine ACI looks to alleviate that by mapping application level language on policy, like the left column, to automated infrastructure provisioning using the constructs in the right column. Here comes part 3 of my ridiculously long notes taken from the ACI boot camp with Cisco this week. provide secure micro-segmentation of all their workloads.

Use policies and Cisco® ACI to make data centers more flexible and configurable—and deliver far more business value. Hooda, Shyam Kapadia, Padmanabhan Krishnan na Amazon. QFX Series,EX Series,MX Series. Also the config for IGP is omitted here, since you can run whatever you want (also static routing right? yes! but lot of work), in our case we simply setup OSPF in area 0 and point to point interfaces in each link, the only consideration was the MTU, as you may recall from previous post of this series you will need to tune up MTU to be able to send a VXLAN packet inside, you can do the math by. Compre Using TRILL, FabricPath, and VXLAN: Designing Massively Scalable Data Centers (MSDC) with Overlays (Networking Technology) (English Edition) de Sanjay K. The VXLAN framework was created by Storvisor, Cumulus Networks, Arista, Broadcom, Cisco, VMware, Intel, and Red Hat. Some battery packs can output enough power, but without the 1. pdf scenario without VXLAN multipath you should. The big difference between ACI and stand-alone VXLAN is that ACI is a centrally managed, completely programmable software defined networkOK, one of the big differences. This feature is not available right now. Why choose Cisco Nexus 9000 switches? You may list at least 10 reasons, such as fast, scalable, secure. Practices BRKDCT-1301. Cisco has provided a complete solution based on this VXLAN Overlay. —May 16, 2014— Cisco today announced it is delivering on its vision for Application Centric Infrastructure (ACI) through the release this summer of the Application Policy Infrastructure Controller (APIC), ACI fabric mode for Cisco Nexus® 9000 Series switches, UCS Director. Therefore, it looks as if ACI LEAF is sending a packet with bogus VLAN without VxLAN encapsulation in SPAN. While VLANs stop at a router, VXLAN is a tunneling protocol that can go over routers, allowing VXLAN to extend a layer 2 subnet within or to another data center. The service control node supports dynamic expansion without service interruption. ACI may use other things in addition to VXLAN for tenant isolation, but it seems to me that the use of VXLAN makes the most sense. VXLAN Benefits, How Does VXLAN Work?, VXLAN Implementation Methods, Using QFX5100, QFX5110, QFX5200, QFX5210, EX4300-48MP, and EX4600 Switches with VXLANs, Changing the UDP Port on QFX5100, QFX5110, QFX5200, QFX5210, and EX4600 Switches, Controlling Transit Multicast Traffic on QFX5100, QFX5110, QFX5200, QFX5210, and EX4600 Switches, Using an MX Series Router. So in the case of VXLAN packets, it will look at the outer headers and be completely oblivious (as expected) to the tunneled traffic inside. After doing the process a few times without any success, and AVE not getting pushed to vCenter, I enabled infra-vlan on the AEP towards the host, which is a requirement when running VXLAN, and there it goes. VXLAN utilizes a 24-bit VXLAN header, shown in the diagram, to identify virtual networks. The ACI fabric exhibited impressive resiliency to, and quick re-convergence around, failed links and switches. VXLAN EVPN - VxLAN is an overlay technology that encapsulates a Layer 2 frame into UDP header to extend your Layer 2 domain over a Layer 3 underlay infrastructure.

Cisco Nexus 9000 Series Switches can run in ACI mode or NX-OS mode. Ivan Pepelnjak (CCIE#1354 Emeritus), Independent Network Architect at ipSpace. For example, VxLAN vs. It goes without saying I know most people here would be against NSX. (I think the word was "enhancement. Each host will have one VTEP, or multiple VTEPs, depending on the VXLAN vmknic teaming policy you've chosen. Cisco ACI enables customers to build and control the physical underlay fabric. ACI Worldwide, the Universal Payments (UP) company, powers electronic payments for more than 5,300 organizations around the world. Cisco Video Portal. ACI Fabric decouples the tenant end-point address, it’s “identifier”, from the location of that end-point which is defined by it’s “locator” or VTEP address Forwarding within the Fabric is between VTEPs (ACI VXLAN tunnel endpoints) and leverages an extender VXLAN header format referred to as the ACI VXLAN policy header. In NX-OS mode Cisco Nexus 9000 Series Switches function as classic switches. Understanding the. Why Cisco is Warming to Non-ACI Data Center SDN There are three basic ways to do software defined networking in a data center. This helps span VXLAN awareness and maintain the ease of VXLAN management. Solved: Hi Everyone, Could you please point me to a document which explains how VXLAN operates on Nexus9000 in ACI mode? I know that the VXLAN operates different in NX-OS mode and ACI mode. 0/15 by default can be the same across different sites. It's the same with CVX (their eAPI). • The ACI VXLAN overlay, which enables the decoupling from the physical network and the creation of virtualized L2 segments regardless of the endpoint location Cisco ACI Traffic Monitoring Cisco ACI presents network architects and operators with new levels of scale, automation and ease of deployment. Ivan Pepelnjak (CCIE#1354 Emeritus), Independent Network Architect at ipSpace. Various Big Data analytics and mining technologies are evolving, bringing with them a rise in personalized applications and shorter product lifecycles. ACI can provide a secured/automated fabric and NSX end-to-end network services available in multiple locations including a public cloud. Only that it is only achieved when using VXLAN/EVPN.

VXLAN offload results in greater than 2X throughput improvement with approximately 50% lower CPU overhead. It uses VLAN or VXLAN encapsulation, so - a pretty standard setup. Download "Strategic Datacenter Design February, 2014. Original VXLAN defines that BUM frames are carried over IP multicast packet. In the second part, I will focus specifically on VXLAN as a Data Center Interconnect. The VXLAN segments are independent of the underlying network topology; conversely, the underlying IP network between VTEPs is independent of the VXLAN overlay. Additionally all functionality is exposed through an open RESTful read/write API allowing any system to integrate management with or without Cisco engineering resources. VXLAN implementations in hypervisors switches; Integration with vCloud Director; Large-scale VXLAN solutions, including unicast mode VXLAN and EVPN-based scale-out architectures; Hardware VXLAN gateways and VLAN-to-VXLAN integration options; Use of VXLAN in data center fabrics (Arista, Cisco ACI) and OpenStack Quantum. VXLAN will make it. ACI Fabric “Federation” (unifying multiple ACI fabrics into one) is not currently supported. But any SDN kind of fabric is a single vendor lock, while with Juniper you can at least manually build your fabric without a controller software (It was a piece of shit from Cisco, certainly it. VXLAN Deployment Scenarios VXLAN is typically deployed in data centers on virtualized hosts, which may be spread across multiple racks. SDN & Cisco ACI A brief introduction ; 2. Conceptually, the NSX distributed firewall is like having many small firewalls, but without the burden of maintaining many small firewall policies. Frame encapsulation is done by an entity known as a VXLAN Tunnel Endpoint (VTEP. See the complete profile on LinkedIn and discover Subbiah’s connections and jobs at similar companies. This allows the data center network to grow without the risk of creating too large a failure domain. This header provides for up to 16 million virtual L2 networks. LISP offers a higher scalability and traffic optimization than BGP. My assumption is that for some reason, Cisco seems to have hired the App Development experts to develop the ACI GUI and the ACI design and configuration guides, and the final product turned out to be hard to digest to both, DevOps and Networking professionals. Fabric builder is a turn-key function for easy Day-0 provisioning of data center network deployments. The VMware guys are pushing for NSX with their implementation of VXLAN L2VPN (it seems to lack redundancy?). One Reply to "Cisco ACI Multi-Pod (Pt. Note: If the participant fails to meet at least 75% attendance per module and/or fails to sit for an assessment or for any other reason where funding is not approved, company / trainee is required to reimburse ACI the funded portion of the course fees.

ACI MultiPod was first designed to enable the spread of ACI Fabric inside a building (into two or more Pods), let's say in two rooms at different floors, without the need to connect all the Leafs from one room to all the Spines in the other room. ACI relies on an VXLAN overlay to carry the data packets and policies inside the ACI fabric, and up to the WAN edge device (if WAN edge is configured accordingly), hence, some network transport behavior could be similar to VXLAN EVPN standalone, but it’s very difficult to make a generic rule. However, ACI is much more than a mere VXLAN overlay; here ACI specific functions will be discussed more in detail. VXLAN is an encapsulation and overlay protocol that runs on top of existing networks. This post is meant to summarize the available ACI Software features, by release, and be used as a quick reference guide. With VMware's NSX using VLXAN (among other overlays) as a core part of its overall solution and the recent announcement of Cisco's Application Centric Infrastructure (ACI) and the accompanying Nexus 9000 switch, both of which leverage VXLAN for. 1Q VLAN 50 Normalized Encapsulation Localized Encapsulation IP Fabric Using eVXLAN Tagging PayloadIPeVXLANVTEP • All traffic within the ACI Fabric is encapsulated with an extended VXLAN (eVXLAN) header • External VLAN, VXLAN, NVGRE tags are mapped at. So yes, again, they can't figure out how to do it without custom silicon. UDP is used as a convenient format in terms of programming and its use of src/dst port provides a ready means to both multiplex connections as well as a means by which intermediary forwarding elements can hash connections over parallel links. Contiv is all open sourced. VXLAN (NSX) over eVXLAN (ACI) seems to be a uneccessary complication but on the other hand both can play a different roles. This market traction is important as VXLAN is the de-facto standard for overlays in the industry. If I have missed any other resources, reach out to me on Twitter and I will add them. This may also be known as a Clos fabric. The ACI+NX-OS Essentials, Advantage, and add-on licenses are supported for Cisco Nexus 9000 Series switches beginning with Cisco NX-OS Release 9. With this model, ACI uses a full mesh, single hop, loop-free topology without the need to use the spanning-tree protocol to prevent loops. 1Q VLAN 50 Normalized Encapsulation Localized Encapsulation IP Fabric Using eVXLAN Tagging PayloadIPeVXLANVTEP • All traffic within the ACI Fabric is encapsulated with an extended VXLAN (eVXLAN) header • External VLAN, VXLAN, NVGRE tags are mapped at. Security Interest Group Switzerland is an independent interest group without any membership fees or other commitments. The idea of Layer 2 loops and data plane MAC address learning that led to development of Spanning Tree is not the case here. As before, the VXLAN VTEPS still provide layer 2 over layer 3 transport, but now the NSX is managing BGP and BUM traffic handling. Get Started. Failed controllers have no impact on data flows; no data is lost. Location Services Now that we have a way to keep tenants isolated and encapsulate their packets across a network, the source leaf switch would need to know where to send a packet. This Question and Answers guide will help you to understand Cisco ACI from basics to advanced level and give confidence to tackling the interviews with positive result. Julian Lucek is a Distinguished Systems Engineer at Juniper Networks, where he has been working with many operators on the design and evolution of their networks.

The goal is to show students how to use the ACI in a live working environment, first starting with its fundamental operation, and then focusing on integration and migration scenarios. Why is Cisco Pushing LISP in Enterprise Campus? From the business perspective because it is sticky to Cisco. Hooda, Shyam Kapadia, Padmanabhan Krishnan na Amazon. LACP = Single VTEP using multiple uplinks Fail Over = Single VTEP using one uplink Load Balance = Multiple VTEPs each using one uplink. My question is: what should I do with post-tensioned slab, for which there are only tendons and there is no distinction between top and bottom rebar? I know that ACI 318 mostly covers RC design but not prestressed design. Understanding the. After a practical introduction to ACI concepts and design, the authors show how to bring your fabric online, integrate virtualization and external connections, and efficiently manage your ACI network. LAB : Complete the following task : Configure the Underlay network between Leaf -1, Leaf -2, Leaf -3, Leaf -4, Spine-1, and Spine 2 by OSPF. VXLAN is an encapsulation technology that allows UDP layer 2 over layer 3. Arista, Broadcom, Intel, VMware and others developed the VXLAN specification to improve scaling in the virtualized Data Center. In this case VMs can be moved without issues but we must consider how to recover from a. like buying a fancy television without a remote control. In "normal" network if you are connecting virtual machine to get the connection to some other virtual machine on different subnet, you need to use a layer 3 router to make a connection between networks. How does VXLAN work? It's easy to be overwhelmed with this technology, get the basics down with this video and it should give you a high level walk through of how hosts communicate through VXLAN. In the last year I’ve had numerous customers talk to me about ACI and ways to implement it without having to redesign how their applications are written. Additionally, ACI alleviates the need for gateway servers by providing gateway, bridging, and routing functions for untagged, VLAN, VxLAN, and NVGRE on any port. The spine switches maintain a DB, called the Global Station Table, of IP’s across the entire fabric. 1Q VLAN 50 Normalized Encapsulation Localized Encapsulation IP Fabric Using eVXLAN Tagging PayloadIPeVXLANVTEP • All traffic within the ACI Fabric is encapsulated with an extended VXLAN (eVXLAN) header • External VLAN, VXLAN, NVGRE tags are mapped at.

This Data Center Application Centric Infrastructure (ACI) Fundamentals course is a 5-day Instructor-led training course that is designed for systems & field engineers who install & implement the Cisco Nexus 9000 Switches in ACI mode using the updated 2. Experience with products from vendors such as Cisco (NX-OS, IOS, CatOS, ACI, ISE), Juniper, F5, Palo Alto, A10 Networks; Experience implementing security solutions such as web application firewalls, deep packet inspection, intrusion protection, DoD PKI, and VPNs are required. ACI is a great concept in a Greenfield deployment but what about Datacenters that want to easily manage VXLan or gain more application visibility. VTEP (VXLAN Tunnel End Point) is a logical interface. ACI Leaf Engine, and ACI Spine Engine - without their custom silicon, you don't have ACI. VXLAN ID (called VXLAN Network Identifier or VNI) is 24-bits long compared to 12-bits of VLAN ID. Last modified by NimishDesai on Apr 22, 2015 12:41 PM. Emin has 5 jobs listed on their profile. While NSX can leverage existing network infrastructure without the need for new hardware - there are some real benefits to being deployed alongside Cisco ACI. When implementing a large-scale Cisco network, monitoring tools typically rely upon. In 10 days without any assistance from F5 VXLAN NVGRE LAYER 2–4 10-BOPRESO-AG Orchestration Accelerate deployments and reduce operational risk_FINAL_vv. SAN JOSE, Calif. They can also use ACI mode, with hardware infrastructure ready to support the Cisco ACI solution, to take full advantage of an automated, policy-based, systems management approach using Cisco ACI. With VXLAN Multipod geographically dispersed across two distant locations, the overlay data plane is extended from end-to-end (from leaf node in site A to leaf node in site B). Use policies and Cisco® ACI to make data centers more flexible and configurable—and deliver far more business value. This is regarding the comparison of Cisco ACI vs NSX SDN. Within NSX, VXLAN is an overlay network only between ESXi hosts and VM's have no information of the underlying VXLAN fabric. On the interface, peering protocol is configured along with route redistribution and inbound/outbound filtering and classification rules.

This is required for VXLAN encapsulation support on the Nexus 5600s. This post is meant to summarize the available ACI Software features, by release, and be used as a quick reference guide. While VLANs stop at a router, VXLAN is a tunneling protocol that can go over routers, allowing VXLAN to extend a layer 2 subnet within or to another data center. Solved: Hi Everyone, Could you please point me to a document which explains how VXLAN operates on Nexus9000 in ACI mode? I know that the VXLAN operates different in NX-OS mode and ACI mode. One Reply to "Cisco ACI Multi-Pod (Pt. Also the config for IGP is omitted here, since you can run whatever you want (also static routing right? yes! but lot of work), in our case we simply setup OSPF in area 0 and point to point interfaces in each link, the only consideration was the MTU, as you may recall from previous post of this series you will need to tune up MTU to be able to send a VXLAN packet inside, you can do the math by. By creating a new way to link networks and applications in a highly virtualized data center, Cisco ACI is considered as “a revolutionary re-thinking of how to provision and manage data center networks”. Every bridge domain needs to be associated with a context. Julian Lucek is a Distinguished Systems Engineer at Juniper Networks, where he has been working with many operators on the design and evolution of their networks. I was putting slides together for my upcoming talk and there is some confusion about VXLAN in particular, how many VLANs it provides. ACi External Domains :L2Out; VXLAN. VXLAN is at the heart of ACI and its headers provide all the information required to pass the packets between endpoints and enforce desired policy. The VMware guys are pushing for NSX with their implementation of VXLAN L2VPN (it seems to lack redundancy?). Cisco ACI vs VMware NSX: Which is better? We compared these products and thousands more to help professionals like you find the perfect solution for your business. This is the real hard topic to cover, not in theory or technology but really in config section. At ingress, ACI encapsulates external VLAN, VXLAN, and NVGRE packets in a VXLAN packet. Review all of the job details and apply today!. 自动化业务模式: ?网络计算联动以及网络自主定义业务模板方式 都支持 ?支持GBP(Group Based Policy, V2R1)&Neutron面向应用的业务模型 Cisco:ACI(VXLAN方案,N9K交换机、 APIC控制器)和DFA(TRILL, N7K交换机, DCNM控制器)两套方案、控制器和交换机, 无法兼容和平滑升级. Nexus Fabric Manager builds and self. 0 update DC VT Nov 2015 Session Abstract and Objectives Virtual Topology System (VTS) is a software solution that provides a single pane of glass to manage and operate VxLAN overlay services for a multivendor data center. Therefore, it looks as if ACI LEAF is sending a packet with bogus VLAN without VxLAN encapsulation in SPAN. Low Prices, 24/7 online support, available with World Wide Delivery. SDN & Cisco ACI A brief introduction ; 2. Rather ACI is an entire SDN solution wrapped around the idea that IT applications are the most important thing in an organization. Cisco has provided a complete solution based on this VXLAN Overlay. The primary physical difference between ACI and NSX is that NSX maintains the VTEPS as VMKernel ports that belong to the ESXi hosts that have virtual wires or virtual switches. You must use VXLAN to maximize the load balancing of the traffic inside the fabric. Cisco Nexus 9300 - VXLAN with BGP EVPN Control Plane - Part 1 September 15, 2015 February 22, 2019 Jesse Cisco , DCI , EVPN , Routing , VXLAN For the last few weeks I have been configuring, testing and taking new Cisco Nexus 9300 (Nexus 9000) platform with VXLAN and BGP EVPN control plane into use. The ACI fabric exhibited impressive resiliency to, and quick re-convergence around, failed links and switches. event Correct Answer: C QUESTION 35 You have a network that has three subnets You migrate the network to a Cisco ACI fabric You want to bridge the three subnets without changing the IP addresses of the endpoints The default gateway for the endpoints does not sit on the ACI fabric. Created by nikhilvmw on Apr 17, 2015 10:34 AM. We can see the same thing today with what were once purely software overlays (VXLAN specifically) that were encapsulated in soft-switches. VXLAN BGP EVPN Layer 2 Fabric. Download Document. If your business requires integration of non-VMware hosts or physical servers, the Cisco ACI fabric will be able to normalize these packets and forward them without performance penalty. This is a compilation of useful and clarifying notes that I've gathered related to Meet-Me conferencing. But any SDN kind of fabric is a single vendor lock, while with Juniper you can at least manually build your fabric without a controller software (It was a piece of shit from Cisco, certainly it. ACI looks like a single device to the rest of the network. This is regarding the comparison of Cisco ACI vs NSX SDN. They can also use ACI mode, with hardware infrastructure ready to support the Cisco ACI solution, to take full advantage of an automated, policy-based, systems management approach using Cisco ACI. Also, the ALE to my understanding provides buffers 'or' additional functionality (Could easily be a misunderstanding of perception). or primer into the basic concepts and terminology. ACI for Service Providers (SPACI) is a 5-day Cisco ACI training course that provides ACI use cases for Service Provider environments including policy-driven configurations and design details, multi-tenant internal and external network integration and migration, routing protocol exploration, security implications, and disaster recovery solutions. net, has been designing and implementing large-scale data communications networks as well as teaching and writing books about advanced internetworking technologies since 1990. VXLAN header and send it to the destination host VTEP over the Transport VLAN. With a configurable VXLAN port, users can choose the port configuration of the two products, used in combination, for their particular environment. Symptom: Traffic with a UDP destination port of 8472 is dropped on ingress by the ACI fabric. VXLAN implements a tunneling mechanism using mac-in-udp to transport L2 over a L3 network (by using a L4 encapsulation there are great benefits). With the success of Cisco ACI in the market and the need for microservices, integration between ACI and Contiv was inevitable. VXLAN VXLAN (Virtual eXtensible Local Area Network) addresses the above requirements of the Layer 2 and Layer 3 data center network infrastructure in the presence of VMs in a multi-tenant environment. All of the training … Continue Reading. – a packet going across the ACI fabric will be first encapsulated by NSX at the vSwitch with a VXLAN header for VM to VM connectivity. This header provides for up to 16 million virtual L2 networks. VXLAN will make it. This helps span VXLAN awareness and maintain the ease of VXLAN management.
