Domain Subobjects for Resource Reservation Protocol - Traffic Engineering (RSVP-TE)

Abstract

The Resource Reservation Protocol -Traffic Engineering (RSVP-TE) specification and the Generalized Multiprotocol Label Switching (GMPLS) extensions to RSVP-TE allow abstract nodes and resources to be explicitly included in a path setup. Further, Exclude Route extensions to RSVP-TE allow abstract nodes and resources to be explicitly excluded in a path setup.

Domain Subobjects for the Path Computation Element Communication Protocol (PCEP)

“…OSPF Area ID 7 IS-IS Area ID Note: Identical subobjects are carried in RSVP-TE messages as defined in [RFC7898].…”

“…PCEP ERO subobject types correspond to RSVP-TE ERO subobject types as defined in [RFC3209], [RFC3473], [RFC3477], [RFC4873], [RFC4874], and [RFC5520]. The subobjects related to the domain sequence are further defined in [RFC7898].…”

“…Further, IANA has added a reference to this document to the new RSVP numbers that are registered by [RFC7898], as shown on <http://www.iana.org/assignments/rsvp-parameters>.…”

“…The subobjects defined in this document SHOULD be supported by RSVP-TE. [RFC7898] extends the notion of abstract nodes by adding new subobjects for IGP areas and 4-byte AS numbers.…”

“…This is a companion document to Resource Reservation ProtocolTraffic Engineering (RSVP-TE) extensions for the domain identifiers [RFC7898].…”
