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

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

Cisco IOS XR MPLS Configuration Guide for the Cisco CRS Router, Release 5.3.x

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