Abstract
A network component comprising at least one processor configured to implement a method comprising transparently snooping a path control message comprising a first path identifier, wherein the path control message is sent between a plurality of routers and is not intended for the network component, analyzing a plurality of frames each comprising a second path identifier, and diverting at least some of the frames away from at least one of the routers, wherein the second path identifier in the diverted frames matches the first path identifier. Included is a method comprising configuring a bypass path by snooping a control frame comprising a label switched path (LSP) identifier, and routing a plurality of data frames associated with the LSP identifier to the bypass path without routing any subsequent control frames associated with the LSP identifier to the bypass path.
