Multiple uplinks via MPLS VPN using iBGP

[omolo]

We are implementing an mpls vpn network for an ISP. We have a problem in getting three uplinks to other isps to work correctly.

We have 3 internet PEs configured to uplink with the service providers.

The routes in the routing table are being ignored and the default route is the only one being used which originates only from one of the service providers. Any ideas on how to get this working right?

try to use prefix-list,AS number with route maps to filter out the defualt -route

bgp  next-hop and split horizon make  LSR never advertise routing to another LSR, and next-hop makes routing only goes to another AS area ,that make LFIB   LDP  only to find PE , that is why mpls  vpn uses ibgp
