Example: VXLAN with BGP EVPN
The following VXLAN with BGP EVPN example uses a Clos leaf-spine topology with VXLAN tunnel endpoints (VTEPs). 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 spine nodes are in one autonomous system—AS 101. All
leaf nodes are in another autonomous system—AS 100.
● On VTEPs 1 and 2: Access ports are assigned to the virtual network using a switch-scoped VLAN. EVPN is configured using
auto-EVI mode.
● On VTEPs 3 and 4: Access ports are assigned to the virtual network using a port-scoped VLAN. The EVPN instance is
configured using manual configuration mode. The RD and RT are configured using auto mode.
All VTEPs perform asymmetric IRB routing, in which:
● IRB routing is performed only on ingress VTEPs.
● Egress VTEPs perform IRB bridging.
