RSVP-TE extensions for dynamic hostname traversing OSPF routing areas
ZTE Corporation
RFC 5642 defines an OSPF Router Information TLV that allows OSPF Routers to flood their hostname-to-Router-ID mapping information. Sometimes, when the operators create an inter-area MPLS LSP tunnel with Resource ReSerVation Protocol-Traffic Engineering (RSVP-TE), they need the hostname display on the CLI at the ingress node for management and operational reasons. This document describes extensions to RSVP-TE to support hostname-to-Router-ID mapping information traversing areas in an inter-area MPLS LSP tunnel situation.
