This document introduces the Sonet/SDH traffic engineering extensions required for existing IGP protocols in support of Generalized MPLS (GMPLS) signalling as defined in [RFC-3471] and [GMPLS-SONET-SDH]. Using [GMPLS-RTG] as guideline, this memo specifies the GMPLS routing traffic engineering extensions to OSPF for Sonet/SDH networks. Based on the Traffic Engineering (TE) extensions defined in [OSPF- TE], the proposed approach is aligned with link bundling as defined in [MPLS-BDL] and extends the set of Link sub-TLVs proposed in [GMPLS-OSPF] to Sonet/SDH networks. The proposed extensions do not preclude any further integration with the Interface Switching Capability Descriptor specified in [GMPLS-OSPF].
