Assigning a VRF routing instance to a GRE tunnel interface
A GRE tunnel interface can be assigned to an existing user defined VRF. When the VRF is configured on a tunnel, all IPv4 and IPv6 addresses are removed. The tunnel loopback configuration is removed.
Note: ICX 7150 devices do not support tunnels. This task is not supported for ICX 7150 devices.
To assign the VRF named VRF1 to tunnel 1, enter the following commands.
device(config)# interface tunnel 1 device(config-tnif-l)# vrf forwarding VRF1
