In networks where a Path Computation Element (PCE) is used for path computation, it is desirable for the Path Computation Clients (PCCs) to discover dynamically and automatically a set of PCEs along with certain information relevant for PCE selection. RFC 5088 and RFC 5089 define the PCE discovery mechanisms based on Interior Gateway Protocols (IGP). This document defines extensions to BGP for the advertisement of PCE Discovery information. The BGP based PCE discovery mechanism is complementary to the existing IGP based mechanisms.
