vni vni
Parameters
vni
Enter the virtual-network ID, from 1 to 16,777,215.
Default Not configured
Command mode EVPN-EVI
Usage
information
Use this command in EVPN-EVI mode to configure an EVPN instance with RD and RT values to an overlay
VXLAN virtual network.
Example
OS10(config)# evpn

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 65001.
All leaf nodes are in another autonomous system—AS 65002.
● 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 VTEP 3: 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-EVI mode.
● On VTEP 4: Access ports are assigned to the virtual network using a port-scoped VLAN. EVPN is configured using manual
configuration mode, including the EVPN instance, RD, and RT.
