Hi, The unsignalled backup LSP is that described in the draft-swallow-rsvp-bypass-label-01.txt. Basically, a bypass tunnel which goes to the appropriate merge node is created, based upon a CSPF computation. Depending upon the possible implementations, that bypass tunnel could have been statically configured or created dynamically when the need for one arose. Once a bypass tunnel exists, the unsignalled backup LSP can be created once the label record sub-object in the RRO from the merge node has been received at the PLR. Only local configuration at the PLR is necessary to create the unsignalled backup LSP; no RSVP signalling is necessary. Hope this helps, Alia Atlas At 09:25 AM 8/9/01 -0400, Jie Zou wrote: > >Hi, > >I am reading the draft of "MPLS RSVP-TE Interoperability for Local >Protection/Fast Reroute."
