Hi All,
I am not able to configure the neighbor ip-address as-override command on my cisco 2821 router.
My router ios - c2800nm-advsecurityk9-mz.124-15.T9.bin.
What should I do for that command to work on my router?
Solved! Go to Solution.

Jon,
Sorry.
I am not able to add "neighbor ip-address as-override" command under bgp configuration.
Just to clarify, the as-override feature is available for MPLS configurations and is configured under the "address-family ..." subsection under the router bgp
7200(config)# router bgp 65100
7200(config-router)# neighbor 192.168.7.1 <--- as-override cannot be configured here
7200(config-router)# address-family ipv4 vrf TEST
7200(config-router-af)# neighbir 192.168.7.1 as-override
Apologies if you already knew this.

That's weird, you should be able to. What error message do you get when you try to configure it ?
Under the router bgp

Hi Jon,
Thanks for your valuable reply.I got clarified.
What is the difference between the MPLS and BGP configuration. Do share if you have any document.
04-21-2010 11:13 AM
MPLS uses BGP or more specifically MP-BGP between PE routers to pass VRF/VPN information.
What exactly are you trying to do ?

Jon,
I am facing network issue with one of my MPLS service provider.
The specific network AS travell path is repeating.
In the show ip bgp output we found that the AS is repeating
Ex
CE-ROUTER#show ip bgp 10.180.8.64
BGP routing table entry for 10.180.8.64/26, version 46224
192.168.255.101 (metric 12) from 192.168.255.101 (192.168.255.101)
Origin incomplete, localpref 120, valid, external, best
1 6755 4655 32496 64547 65247
remote-as for my CE is 6755.
As this AS 6755is repeating I asked my service provider to add the command allowas-in in PE router.
Instead my service provider asked me to add the command as-override command on my CE router.But my router is running BGP and there is no MPLS configuration.
If I have some document to understand the difference between MPLS and BGP configuration I can clarify the same to my Service provider.
Rgds,
Gopi

Hi,
No use of adding "neighbor
can you post your setup please..
whenever you advertise network into MPLS cloud via your Site A CE BGP, it will advertise into the MPLS cloud with your AS number, then the same bgp update has to send your another site Site BCE router.Now the Site B CE router won't accept the routes which is advertising from site A because of the same AS number.
In this scenario the ISP will replace your AS with their AS by the use of "neighbor
Thanks
