Trying to get VRF forwarding on an interface in Cisco IOS 15.4. We currently have a router with 15.2 and have no trouble with it:
interface FastEthernet0/0/3
switchport access vlan 3
ip vrf forwarding INTERNAL
no ip address
But when I try to configure this on the 15.4 router, I get an error:
Test(config)#int f0/1/3
Test(config-if)#ip vrf forwarding INTERNAL
^
% Invalid input detected at '^' marker.
Test(config-if)#
IP vrf isn't an option:
Test(config-if)#ip ?
Interface IP configuration subcommands:
address Set the IP address of an interface
admission Apply Network Admission Control
auth-proxy Apply authentication proxy
ddns Configure dynamic DNS
device IP device tracking
dhcp Configure DHCP parameters for this interface
igmp IGMP interface commands
rsvp RSVP Interface Commands
Test(config-if)#ip
I do have vrf configured in the global:
ip vrf INTERNAL
description Trusted Network
rd xxxxx:10
!
ip vrf INTERNET
description Internet Traffic
rd xxxxx:20
inter-as-hybrid
Any ideas what I'm missing here?
