JNCIP-ENT lab 17 of 19

EVPN VXLAN and ESI multihoming

Stretch a VLAN across a routed fabric with EVPN-VXLAN, read route types 1 to 4 as they appear, dual-home a switch with an all-active ESI LAG, and fail a link.

Run this lab

It needs Professional: its 6 nodes are set to 15 vCPU and 18,176 MB in total.

In your workspace: Shared, then JNCIP-ENT JN0-650 guided labs, then 17 - EVPN VXLAN and ESI multihoming

Run it on Professional from £7.50 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 15 vCPU and 18,176 MB together. Every lab plan includes every guided lab.

The scenario

Northmere's data centre has grown past one spanning tree. You'll stretch a VLAN across a routed fabric with EVPN-VXLAN: the routed underlay stays simple, VXLAN carries Ethernet frames over it, and BGP EVPN tells each switch where every MAC address is. You'll read each EVPN route type as it appears, and then dual-home a server switch with no MLAG or spanning tree between the two leaves.

OSPF already runs in the underlay. All three switches are in AS 64600. These images print requires 'bgp' license and requires 'vxlan' license warnings, and they don't stop anything here.

What you’ll practise

  • Configure an iBGP EVPN overlay
  • Map a VLAN to a VNI
  • Explain EVPN route types 1, 2, 3 and 4
  • Configure all-active multihoming
  • Read a designated forwarder election and mass withdrawal

The tasks

  1. Map a VLAN to a VNI
  2. Bring up the EVPN overlay and read type 3
  3. Dual-home CE1 with an ESI LAG
  4. Read type 2 and the data path
  5. Fail a leaf link

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 JNCIP-ENT JN0-650 guided labs.

  3. Open 17 - EVPN VXLAN and ESI multihoming 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.
