Re: OSPF in MPLS vpn

Hi Carlos, its a normal behavier as petr says, LSA remains in
database, but routes doesnt install in routing table, and i think that
there are 3 solutions to this,

1) Create te VL between PE and CE in Area 1.
2) Dont use area 1 and configure A 0 in all routers connected to
superbackbone (PEs).
3) Create 2 ospf process in CE redistributing between them.

Horacio.
