I am having an issue with only receiving a partial routing table at a new site connected via Verizon's MPLS service.
The routing protocol used for PE-CE is BGP. The routers involved are all 2821 running the same version of software - v12.4(11).
The new site receive route information for most of the existing sites, but does not get route info for a few specific sites. The BGP routing configuration is the same at all site except for the site specific information.
Basically, Site D is a new site. Site D receives routing info. for sites B and C, but not A.
Sites A receives route info for sites B and C, but not D.
A trace route from A to D, dies after the PE device at site D. A trace route from D to A fails imediately.
A sample of the BGP routing config is below:
router bgp 1
redistribute eigrp ### metric 20
neighbor x.x.x.x remote-as #####
I'm not sure if the issue is with our routing, or if Verizon's PE is not passing all the routing updates.
For the new site D, use the show bgp neighbor command to see the routes being received from the provider peer and to confirm what site D is sending to the provider (you didn't mention whether sites B and C see D).
Assuming there's no inbound BGP filters, route maps, etc. on either site A and D, then if you haven't already, you could try a bgp clear inbound at both sites A and D. If routes still not there, might be time to contact MPLS vendor.
