Hmmm.... Thanks for the responses! I understand that in the two diagrams I supplied: Diagram 1> (Ingress) A --> B --> C (Egress) Diagram 2> A --> 1 --> 2 --> B --> 3 --> C 1, 2, and 3 could be bridges rather than routers (thanks Anoop). I just want to wind out if there are actually MPLS setups out there that look like Diagram 2 rather than like Diagram 1. From the responses, I would guess that the answer is "Yes", but please correct me if I'm wrong! -AMT -----Original Message----- From: Wade Edwards [mailto:wade.edwards@powerupnetworks.com] Sent: Wednesday, February 20, 2002 2:52 PM To: Anoop Ghanwani; Arun M.

Why do you refer to as A, B, and C as hosts instead of routers? -Anoop > -----Original Message----- > From: Arun M.
