I am running an unnumbered core with ISIS, ldp is running fine, if i build a TE tunnel it will not establish, i get " Last Error: RSVP:: Could not add RSVP Path: Operation failed: internal error "
if i give my interfaces real addresses then the tunnels establish ok.
is this a limitation of RSVP, or is there a way to run unnumbered links in the core, and still do TE ?
I can't see anything that says it can't be done !
many thanks, Will
