well, the search can get a bit tricky, but http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cavs/122t cavs.htm
does this sound like your situation? or rather - your IOS version? (begin quote from CCO) Resolved Caveats-Cisco IOS Release 12.2(8)T2 Cisco IOS Release 12.2(8)T2 is a rebuild release for Cisco IOS Release 12.2(8)T. The caveats in this section are resolved in Cisco IOS Release 12.2(8)T2 but may be open in previous Cisco IOS releases. CSCdw84776 When a customer edge (CE) router advertises a route that contains the provider edge (PE)-CE link, the PE router fails to install this route to the virtual private network routing/forwarding instance (VRF) because the route is already registered in the VRF as a connected route. If the connected route is learned from the redistribution of connected routes to the Border Gateway Protocol (BGP) through the external Border Gateway Protocol (eBGP), the BGP on the PE router marks the route with Routing Information Base (RIB) failure and prevents the route from being advertised to other peer internal Border Gateway Protocol (iBGP) PE routers. This behavior causes a loss of connectivity from the local connected route to the remote sites. Workaround: Source the route on the PE router. Do not allow the CE router to advertise the route that connects the PE and the CE routers. This condition does not occur if eBGP is not configured between the CE and PE routers and if a routing protocol such as the VRF, Interior Gateway Protocol (IGP), Open Shortest Path First (OSPF), or Routing Information Protocol (RIP) is used.
