Paul,

Generalized MPLS defines procedures for bi-directional LSP setup.

HI Paul,

I believe RSVP is never intended to set up two LSPs using one single
operation.  We will have to use two RSVP signalling operations to set up
the two LSPs, one for each direction, even if the PVC may be used
bidirectionally.

Subject:  MPLS LSPs and ATM PVCs


Hello,

I have a question about MPLS and ATM. ATM point-to-point PVCs can be
either uni-directional or bi-directional. MPLS LSPs are only
uni-directional. Is there any work being done concerning bi-directional
LSPs, for example, to allow two LSPs to be established by a single RSVP
signalling operation?

I've just joined the list, so apologies if this has already been
discussed.

Thanks,
Paul
