Abstract

For scalability purposes a network may comprise multiple IGP areas. An inter-area TE-LSP is an LSP that transits through at least two IGP areas. In a multi-area network, topology visibility remains local to a given area, and a head-end LSR cannot compute alone an inter-area shortest constrained path. One key application of the Path Computation Element (PCE) architecture is the computation of inter- area TE-LSP paths. In this context, this document lists a detailed set of PCE Communication Protocol (PCECP) specific requirements for support of inter-area TE-LSP path computation. It complements generic requirements for a PCE Communication Protocol.
