Step 2 – Associates interface into VRF (R1) R1

configure terminal interface f0/0 ip vrf forwarding green ip address 172.16.14.1 255.255.255.248 ! interface 1/1 ip vrf forwarding green ip address 10.1.12.1 255.255.255.252 ! interface 2/1 ip vrf forwarding green ip address 192.1.13.1 255.255.255.248 ! interface 3/0 ip vrf forwarding green ip address 150.15.15.1 255.255.255.248 !
