(config)#exit | Exit configure mode. |
(config)#interface eth1 | Enter interface mode |
(config-if)#ip vrf forwarding vrf1 | Associate eth1 to vrf1. Use no ip vrf forwarding vrf1 for un-configuration |
(config-if)#ip address 3.3.3.2/24 | Configure the IP address 3.3.3.2 to eth1 |
(config-if)#commit | Commit the candidate configuration to the running configuration |

Adding a Static Route
#con t | Enter the router configuration mode |
(config)# ip route vrf vrf1 20.20.20.0/24 eth1 | Add static route in vrf1 with eth1 as exit interface |
(config-if)#commit | Commit the candidate configuration to the running configuration |
