Does juniper supports RSVP signalled LSP's tunneled in the core over 1
RSVP LSP.

------R1-----------R2---------R3----core cloud----R4------R5-----R6-----

- All routers in same OSPF domain
- R1 has for example 10 RSVP tunnels towards R6 but they should all be
tunneled over 1 LSP R3-R4

Thanks
Bert

Hannes,

I thought that Bert wanted _RSVP_ established LSPs over one RSVP established
LSP. Please correct me if I'm wrong but LDP tunneling is not what he's aking
for (all LDP tunneling does is allows establishment of LDP peer sessions
over RSVP LSPs). I'm not quite sure if RSVP over RSVP LSP is possible at
all. :)

Could you please comment?

Thanks ;)

sorry seems i was reading to fast; LDP tunneling actually does not
establish the LDP session over the RSVP tunnel it just sets up
a LDP session between two endpoints of an RSVP session; the
resolver then makes use of the RSVP tunnel;

RSVP over RSVP is currently not supported; can you pls shed some light
why does one want to do RSVP over RSVP ? pls provide an application
example plus drawing;

That was what I meant. :) The LDP tunneling ultimately enables the
transmission of LDP packets over a TE tunnel, instead of default (hop by
hop), which results in the neighbour session establishment, etc. :)

Um, it wasn't me who wanted it, it was Bert. :)
