Configuring Layer 3 Interfaces
This example shows how to create a loopback interface:
switch# configure terminal
switch(config)# interface loopback 0
switch(config-if)# ip address 192.0.2.100/8
switch(config-if)# copy running-config startup-config
Assigning an Interface to a VRF
You can add a Layer 3 interface to a VRF.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).
Assign the IP address for a tunnel interface after you have configured the interface for a VRF.
SUMMARY STEPS
1. configure terminal
2. interface interface-type number
3. vrf member vrf-name
4. ip-address ip-prefix/length
5. (Optional) show vrf [vrf-name] interface interface-type number
6. (Optional) copy running-config startup-config
