hi all,
does anyone who used the IDEO labs implementation of MPLS met the
problem of LSP deletion.
In fact , a RESVERROR is automatically generated for each LSP a while
after trying to release the session.
This implementation uses an extension of the marc greis RSVP
implementation, and it seems t

I noticed that the function "get-node-id-by-addr" can't resolve addresses

Hi,
In the modules of RSVP and RSVP_TE/MPLS that are availables on the net, is
there any PATHError or RESVError exchange and processing, after Admission
Control for example.
In other words, does a case of lack of ressources , is considered in these
modules?
