NOTE:
Follow Steps 1 to 6 to check ping connectivity between combinations of other hosts, and between hosts through
different virtual-network IP addresses.
Example: VXLAN BGP EVPN — Multiple AS topology
The following VXLAN with BGP EVPN example uses a Clos leaf-spine example. The individual switch configuration shows how to
set up an end-to-end VXLAN. eBGP is used to exchange IP routes in the IP underlay network, and EVPN routes in the VXLAN
overlay network. All VTEPs perform asymmetric IRB routing, in which:
● IRB routing is performed only on ingress VTEPs.
● Egress VTEPs perform IRB bridging.
In this example, each node in the spine network 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 102. For leaf nodes, VLT domain 1 is in AS 99; VLT domain 2 is in AS 100.
● On VTEPs 1 and 2: Access ports are assigned to the virtual network using a switch-scoped VLAN. EVPN instance along with
RD and RT values are configured in manual mode.
● On VTEPs 3 and 4: Access ports are assigned to the virtual network using a port-scoped VLAN. EVPN instance along with
RD and RT values are configured in manual mode.
NOTE:
In multiple AS topology, you can configure route targets in an easier way using the disable-rt-asn command
with route-target auto or auto evi commands.
