System and method for multipoint label distribution protocol node protection using a targeted session in a network environment

摘要

A method is provided in one example and includes receiving first address information from a protected node over a first label switched path having a first label. The first address information is associated with a first network element. A second label switched path has been previously established with the first network element. The method further includes establishing a targeted session with the first network element, assigning a second label to the second label switched path, and sending the second label to the first network element over the targeted session.

1. A method, comprising:
receiving first address information from a protected node over a first label switched path having a first label, the first address information being associated with a first network element, and a second label switched path being previously established with the first network element; establishing a targeted session with the first network element, wherein establishing the targeted session with the first network element includes sending a first unicast message addressed to the first network element; assigning a second label to the second label switched path; and sending the second label and a forwarding equivalence class label mapping for the second label switched path to the first network element over the targeted session using a second unicast message.
