Oli, More detail:
I have a standard IP/MPLS backbone with MP-iBGP between PEs loopbacks with IS-IS L2 or OSPF area 0 as IGP. This IGP is extended to some non MPLS routers X. In some backbone links failure, IGP allow MP-iBGP to stay UP via X links (non MPLS). This specific IGP design introduce a L3VPN blackhole that can be solved by IGP prefix filtering or by limiting TTL for MP-iBGP sessions, if possible :) On Wed, Oct 14, 2009 at 2:10 PM, Oliver Boehmer (oboehmer) < [email protected]> wrote: > yes, only supported for ebgp.
