Hi Matias,
 
Sorry I cannot be of more help. This was description of the present
supported features LDP for L3VPNs and BGP.
 
If you require a new feature you can submit an enhancement request through
the normal channels.
 
Gary

Ok, we agree with that...
But our customer need to put MPLS labeled routes ( using LDP as signalling )
in the inet.0. And they don´t want to use BGP as routing protocol.
Thanks

IGP shortcuts (enabling the use of LSPs for forwarding to IGP next hops) is
only supported in traffic engineering (RSVP-TE and Static) and not with LDP.
 
LDP is implemented to provide LSPs between BGP speakers next-hops so that
BGP can be removed from the core so bgp external routes need only be held at
the edge.
 

BGP Next-hop information is stored in inet.0 (IGP learned) and inet.3 (mpls
learned, ldp and rsvp).
  
BGP will look in both of these table to resolve the next-hop.

Hi,
Someone know if it is posible to put MPLS labeled routes ( using LDP as
signalling ) in the inet.0 ?
LDP install routes in the inet.3, where they are only used by BGP.
Something like put traffic engineering bgp-igp in the MPLS statment ( but it
only work for RSVP and static labels )
If it is imposible... why?
Thanks!!
