Route Leaking from VRF´s into the Global table

Hi I am currently looking for a solution for injecting routes into the global routing table from a vrf so that a lookup can occur from the global routing table. The standard procedure for route leaking requires a destination ip address that does not belong to the router itself therefore creating a default route from the vrf to the global loopback address isn´t possible.

Performing the following config:

ip route vrf red global

assuming that that is the next hop address a router in the global table works.

However when trying to get a local route table look up this functionality is not possible.

Does anybody happen to know a work around that would allow this to happen.

Kind Regards,

Josh Halley

Does PE can reach the address I mean the address must has a label in MPLS VPN core.

Re: Route Leaking from VRF´s into the Global table


The PE can reach the as it is part of its global (IGP) routing table. So when trying to reach this ip address directly there are no problems with reachability. What I actually want to do is perform the lookup on the same device that is performing the route leaking rather than an external router. As shown in the example below.

interface ethernet0

ip vrf forwarding

ip address

interface loopback0

ip addresss

Ip route vrf red loopback0 Global

ip route ethernet0

This example however doesn´t work, does anybody know of a way to get this functioning?

Hi Rene,

unfortunately I didn´t find any normal solution to this issue. One hack/work around however would be to create a transit /30 vlan on a switch and connect two interfaces from the same physical router into that vlan. Configuring the first interface in the vrf and the other interface in the global table.


interface FastEthernet0/0

ip vrf forwarding red

ip address

interface FastEthernet0/1

ip address

ip route vrf red

This however isn´t really a nice solution to the problem as you either require two seperate physical interfaces or two trunk interfaces on your router where you can configure the same vlan id.

Anyway hope this solution works for you or you manage to find a better one.

Kind Regards,
