guys, thanks for your imput ..... yes i was loosely discribing MPLS ...it does have all the functions you state... and more , i must be mistaken about the RVSP because i seem to remeber reading somewhere that cisco is favoring RSVP....and that there LDP is based on this but hey i must be mistaken ......... also the RFC you list does not come up as valid ont the ITEF...please can you re-send this many thanks steve >From: "Marc-Andre Giroux" >Reply-To: "Marc-Andre Giroux" >To: [EMAIL PROTECTED] >Subject: RE: Isn't MPLS basically just ATM PNNI, but for layer 3?
