As BGP has been extended for north-bound distribution of routing and LSP path information to PCE, the PCEs may not participate in Interior Gateway Protocol (IGP) for collecting the routing information, thus the IGP based PCE discovery cannot be used directly in these scenarios. This document specifies the BGP extensions for PCE discovery.}, }
