[j-nsp] Estabilishing TE's tunnels between juniper and CISCO

[magno]

Hi Marcio.

If you want to hide your topology behind MPLS, you should use the
"no-propagate-ttl".... you should enable this knob under the protocol mpls
hierarchy and on Cisco box you should enter the command "Cisco(Config)# no
mpls ip propagate-ttl forwarded"...

As this technology is not signaled by any object in RSVP (so it's
interoperable), you should configure it on all your router. You can't enable
it on a per LSP base as well.

Hope this helps.

Massimo.
