摘要:
A method is provided in one example and includes communicating a first request message to a first network element functioning as a point of local repair for a backup label switched path. The first request message includes a first network address having a predetermined value and an indication of a forwarding equivalence class associated with the backup label switched path. The method further includes receiving a first reply message from the first network element. The first reply message includes at least one backup path parameter associated with the backup label switched path.
