Assigning a loopback interface to a non-default VRF instance
After creating a non-default VRF instance you can associate a loopback interface to the VRF instance that you created.
To assign a loopback interface to a non-default VRF, perform the following steps:
1. Enter the loopback interface that you want to assign to a non-default VRF instance.
CONFIGURATION
interface loopback 5
2. Assign the interface to a non-default VRF.
INTERFACE CONFIGURATION
ip vrf forwarding vrf-test
Before assigning a n interface to a VRF instance, ensure that no IP address is configured on the interface.
3. Assign an IPv4 address to the interface.
INTERFACE CONFIGURATION
ip address 10.1.1.1/24
4. Assign an IPv6 address to the interface.
INTERFACE CONFIGURATION
ipv6 address 1::1/64
You can also auto configure an IPv6 address using the ipv6 address autoconfig command.
