Deployment Guide

b. Default route configured in VTEPs pointing to border leaf using an intermediate VNI could be removed. Default route or
external routes could now be advertised to the VTEPs from border leaf using advertise commands under EVPN-IP-
VRF mode.
Example - Route leaking across VRFs in a VXLAN BGP EVPN
symmetric IRB topology
The following VXLAN with BGP EVPN example uses a Clos leaf-spine topology to show how to set up route leaking across VRF
in a symmetric IRB topology.
The following explains how the network is configured:
● All VTEPs perform symmetric IRB routing. In this example, all spine nodes are in one autonomous system and each VTEP in
the leaf network belongs to a different autonomous system. Spine switch 1 is in AS 101. Spine switch 2 is in AS 101. For leaf
nodes, VLT domain 1 is in AS 201; VLT domain 2 is in AS 202. VLT domain 2 is a border leaf VTEP.
