RSVP over unnumbered links, ISIS network

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

William,

RSVP TE on ununmbered interfaces is not supported by IOS.
