vrf
Creates a non-default VRF instance for EVPN symmetric IRB traffic.
Syntax
vrf vrf-name
Parameters
● vrf-name — Enter the name of a non-default tenant VRF; 32 characters maximum.
Default Not configured
Command Mode EVPN
Usage
Information
Configure a non-default VRF for symmetric IRB for each tenant VRF. The tenant VRF is created using the
ip vrf command when you enable overlay routing with IRB; see Enable overlay routing between virtual
networks.
Example
OS10(config)# evpn
OS10(config-evpn)# vrf vrf-blue
Supported
Releases
10.5.1 or later
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.
