VRF routes into IGRP.

mohammedrafiq · ‎07-13-2007

Hi,

I am having issue to redistributing 2 vrf-lite routes into my LAN L3 switches.My topology is as below,

PE router having two bgp peering with my CE,

On CE, I having 2 separet routing tables, which I need forwarding to my 2 LAN swiches running EIGRP.

I did try to redistribute BGP into EIGRP but no route is comming into EIGRP, I also configured Static route to forward my one vrf routes to next hop , but still not working. please see my config on CE.

Please note, we need to keep routes sepreate from CE to two lan L3 switches.

Make sure you either configure a default-metric under the address-family ipv4 vrf xxx or set the metric as part of the route-map as follow:

router eigrp 11

address-family ipv4 vrf lite3

default-metric

address-family ipv4 vrf lite2

default-metric

or

route-map TEST permit

set metric

Redistribution will not take place without this.

Hope this helps,

Mohammed,

On the 3750, Can you do a "show ip ro vrf lite2" and "show ip eigrp vrf lite2 topo".

Also if you could try adding the command "autonomous-system 11" under the address-family ipv4 vrf lite2 to see if it solves the issue.
