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.
The individual switch configuration shows how to configure VRFs in the VTEPs and configure route leaking between VRFs.
For other VXLAN and BGP EVPN configuration, see other examples and the VXLAN section.
Route leaking is performed on the Border Leaf VTEP.
There are three nondefault VRFs present in the network Yellow, Green, and Red.
