Locate ASBR in PCE
Mach. Chen
The ability to compute constrained shortest Traffic Engineering (TE) Label Switched Paths (LSPs) in Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks across multiple domains has been identified as a key requirement. This document specifies a procedure for an inter-AS PCE to locate boundary node within its domain dynamically, which is used for path computation.
