Users Guide

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.
● Route leaking is done between:
○ VRF-Yellow and VRF-Green.
○ VRF-Yellow and VRF-Red.
○ VRF-Yellow and VRF-default (underlay with external router)
NOTE: Route leaking is not performed between VRF-Green and VRF-Red.
