In my understanding, when traffic engineering extensions are enabled, I do not have to use no-cspf.
The Junos implementation is IS-IS enables traffic engineering by default. If I use IS-IS as IGP, I do not have to use no-cspf. Is that right ?
But when I did a lab with RSVP with four routers, 3 are PEs and 1 is P. I enabled RSVP and specified the LSP, but no RSVP session was up until I used no-cspf.
What did I miss here?
thanks in advance !!
