VXLAN EVPN lab 8 of 14

NX-OS VXLAN EVPN

Build VXLAN EVPN on Cisco Nexus 9000v leaves with an Arista spine: features, the NVE interface, the anycast gateway and an L3 VNI.

Run this lab

It needs Standard: its 6 nodes are set to 8 vCPU and 15,872 MB in total.

In your workspace: Shared, then VXLAN EVPN fabrics guided labs, then 08 - NX-OS VXLAN EVPN

Run it on Standard from £5 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 8 vCPU and 15,872 MB together. Every lab plan includes every guided lab.

The scenario

Calder Freight has bought a pair of Cisco Nexus 9000 series leaves for its finance systems, and they'll join the fabric alongside the existing kit. You've built this design on two other operating systems already, so you know what every piece is for. In this lab you'll learn how NX-OS names each piece.

Hosts: h1 10.10.10.11, h2 10.10.10.12, h3 10.20.20.13. Route targets: 65000:10010 and 65000:50001. Anycast gateway MAC: 001c.7300.0001. EVE's labels e1, e2 and e3 are Ethernet1/1, 1/2 and 1/3.

What you’ll practise

  • Enable the NX-OS features VXLAN EVPN needs
  • Configure nve1 with ingress replication through BGP
  • Add an anycast gateway and an L3 VNI
  • Read EVPN state with NX-OS commands

The tasks

  1. Start the lab
  2. Enable the features
  3. Build the layer 2 service
  4. Read the routes
  5. Add symmetric IRB
  6. Find out why ARP suppression needs a reload

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder VXLAN EVPN fabrics guided labs.

  3. Open 08 - NX-OS VXLAN EVPN and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
