vrf forwarding

Assigns a VRF routing instance to an interface.
Syntax
vrf forwarding { vrf-name | overlay-vrf }
no vrf forwarding vrf-name
Command Default

VRF routing instance is not assigned to an interface.

Parameters
vrf-name
Specifies the name of the VRF that the interface is being assigned to.
overlay-vrf
Specifies the routing configuration for the VRF. Overlay routing is not allowed on the default VRF. A user VRF is mandatory when configuring a VE if a VLAN is mapped to a VNI.
Modes

Interface configuration mode

Usage Guidelines

When the VRF is configured on a tunnel, all IPv4 and IPv6 addresses are removed. The tunnel loopback configuration is removed.

The no form of the command removes the VRF routing instance assigned to an interface. IP addresses and protocol configuration on this Layer 3 interface are removed.

Examples

The following example assigns a VRF instance to the Ethernet interface 1/1/1. 

device(config)# interface ethernet 1/1/1
device(config-if-e1000-1/1/1)# vrf forwarding guest

The following example shows how to configure a forwarding VRF named red on an IPsec tunnel interface identified as 1. 

 device(config)# interface tunnel 1 
 device(config-tnif-1)# tunnel mode ipsec ipv4                             
 device(config-tnif-1)# vrf forwarding red
The following example show how to configure a forwarding VRF overlay.
Verify:
device(config)# vrf overlay-vrf
device(config-vrf-overlay-vrf)# rd 1:1
device(config-vrf-overlay-vrf)# address-family ipv4 max-route 128
