VRF Import Not Working?


I am trying to import certain routes from the Global Routing Table to a VRF table without any success.  Could you help?  Thanks.

CAR_A#sh ip route
O IA [110/2] via, 00:25:21, FastEthernet1/0

CAR_A#sh run | in ip prefix
ip prefix-list data-center-net seq 15 permit le 32

CAR_A#sh run | b route-map data-center-net
route-map data-center-net permit 10
match ip address prefix-list data-center-net

CAR_A#sh run | b ip vrf data
ip vrf data
import ipv4 unicast map data-center-net

CAR_A#sh ip route vrf data
Routing Table: data
C is directly connected, FastEthernet0/0.2

As you can see, the vrf data routing table is not learning imported from the Global Routing Table.

Hi Kevin

Can you post the config !!

And also please can you share  the output of

1] Sh ip vrf (name) detail

2] Sh ip bgp vpnv4 vrf (name)

And check whether RD has configured under your vrf.

Re: VRF Import Not Working?


I finally got it working by just reloading the router.  Feels like troubleshooting Windows product now - reboot first!

Now, I got the import working.  I am wondering if there is a dynamic export feature to export VRF routes into Global Routing Table.

Here is the problem.  All sites are connected to a MPLS VPN cloud.  Networks located at the Data Centers are in the Global Routing Table.  Branch offices have several VRFs using VRF-lite, for example, Engineer VRF and Finance VRF.  All VRF-lites are also configured on the data center WAN edge routers.  So far I have managed to import data center networks into both Engineer VRF and Finance VRF using "import ipv4 unicast" command.  How do I export Engineer networks and Finance networks to the data center?  "export ipv4 unicast" does not exist.

Re: VRF Import Not Working?

I finally tried GRE based route leaking on the same router.  I can finally have connectivity between a VRF and the Global Routing Table.

interface Loopback100
 ip address
interface Tunnel100
 ip address
 tunnel source Loopback100
 tunnel destination
router ospf 100
 network area 0

interface Loopback101
 ip address
interface Tunnel101
 ip vrf forwarding 

ip address
 tunnel source Loopback101
 tunnel destination
router ospf 101 vrf 
 network area 0

However, this might not be an ideal solution for the data center as it routes all traffic thru a GRE tunnel.  I will try the cross-over cable trick next.
