IOS-XR config to implement LDP tunneling over RSVP-TE core

[katetranva]

Hello,

I am looking for IOS-XR configuration to tunnel LDP over RSVP-TE core. Do you have a link or pointer on how to do this?  

Someone in this forum posted how to do it for IOS a while back:

 Enable LDP on the tunnel intf. On the headend, config:

int tu0

tag ip

mpls label proto ldp

Enable tailend to accept directed LDP session., On the tailend config:

mpls ldp discovery targeted-hello accept

Thank you,

Kate

You need to enable ldp on the tunnel:

mpls ldp

  interface tunnel-te1000

mpls ldp discovery targeted-hello accept

This is correct, on the tail you need to accept targeted hello's.

The key words here are "LDP Discovery for active targeted hellos".  Juniper call this LDP tunnelling.
