Thanks to all who responded on original question and follow up regarding this issue. To summarize the responses I received.... Given an MPLS LSP: (Ingress) A --> B --> C (Egress) Packets labelled for this LSP by A will be switched along this LSP. However, if there is a lower level MPLS unaware network backing this MPLS network, then packets could be bridged during transit from A to B and from B to C. This will result primarily in increased latency through the network, and should have no other effect. Thanks again! -AMT -----Original Message----- From: Wade Edwards [mailto:wade.edwards@powerupnetworks.com] Sent: Thursday, February 21, 2002 6:44 AM To: Arun M.

They have to be bridges and cannot be routers, in the traditional layer-3 sense. If they were routers, traditional layer-3 devices that don't understand MPLS labels, they would not know what to do with the labeled packets and would drop them. Just making sure we are on the same page. L8r. ------- The MPLS-OPS Mailing List Subscribe/Unsubscribe: http://www.mplsrc.com/mplsops.shtml Archive: http://www.mplsrc.com/mpls-ops_archive.shtml
