Hi guys i have set up a layer 3 vpn across the mpls and have Customer A connecting to Customer A across the MPLS core, I have just set up another PE router on the core and paired them up using MBGP and pairing works and able to ping the loopback address MBGP pairing.
Under sh ip route the routes are coming across but i am unable to ping from customer CE1A to CE3A, same fromt the other end, for the love of god i cant seem to figure it out why they are not pinging
Please ignore the bottom right hand corner of the image, that is part of my next bit
1. I can get routes from CE1A to CE2A and ping across
2.I can get routes from CE3A on CE1A vice a versa (#sh ip route)
3. ping suceesful from PE1 to PE3 (loopback addresses)
4. RD: 1:111 Same across the one customer
5. RT : 1:100 (export and import)
Please help

Hi TTboy,
Which protocol are u using as CE-PE routing one? Did you verify the redistribution? Make sure your PE find the correct next-hop because some IOS have this kind of bug. If you shared more info about the config itself (PE to CE ) it would be easier to help

Hi Thanks you for the reply, I am using Eigrp between the PE and CE, I am not aware of this bug as it was working between PE1 and PE2 (pingable).

I was a bit skeptic in tryingthe Redistribute connected command as it was not need other MBGP pairings, after doing i did try it and it did not make a difference. I did further trouble shooting and since gns3 played up a littel bit i had to do further re code all the commands. re establish the pairing.
Well its fixed as they are able to ping across, can it be due to the duplex being set on auto ? (went through all the P routers to ensure that they were not on auto
Thanks guys for the help
