Re: MPLS VPN Question

Hi Scott,

You wouldn't normally have VRFs on the CE routers. Is that actually in the config or were you just meaning you can see the routes on the CE routers? You should be able to ping between CE and PE routers unless there is some kind of filtering going on so that's a good place to start. If you post your configs (relevant parts) we'll be able to provide some more useful comments.

cheers,
Ben.

Subject: MPLS VPN Question

Hey Group- I just joined the forum a few days ago and have enjoyed the
conversations going back and forth, many active participants!

Anyway I have my first question about MPLS VPN configuration. I just have
a single-customer "Customer A" topology:
(CEA-1)--->(PE1)--->(P)--->(PE2)--->(CEA-2). The mpls and mp-bgp operation
looks good but I am unable to ping between the CE routers. Trying to ping
the P2P links between directly-connected PE and CE routers, from either the
CE or PE on the opposite side of the mpls network. The routes are in the
CustomerA vrf on the CE routers. One weird thing I noticed when I try to
ping between directly-connected PE and CE (CEA1 and PE1) or (CEA2 and PE2),
if I ping from the PE router, it fails. However, if I ping the PE router
from the CE router, it is successful. Not sure if that has anything to do
with it but thought it odd.

I am using gns3, with all 3640 routers running IOS
c3640-jk9s-mz.124-16.bin.

Let me know if configs or any show outputs would help, didn't want to
bombard everyone with them up front. Thanks for any help!

Regards,

Scott
