Create one VRF instance: spoke2. Set the RD and RT values, and associate the VRF with the
corresponding interface.
DES-7200# configure terminal
DES-7200(config)# ip vrf spoke2
DES-7200(config-vrf)# rd 1:100
DES-7200(config-vrf)# route-target export 1:300
DES-7200(config-vrf)# route-target import 1:100
DES-7200(config-vrf)# exit
# Associate the VRF with an interface.
DES-7200# configure terminal
DES-7200(config)# interface gigabitethernet 1/0
# The no switchport command is used to switch the port mode on switches to routed port mode.
It is not applicable to routers. You are not required to run this command on routers.
