es.tid.pce.pcep.objects.ExplicitRouteObject

All Implemented Interfaces:

PCEPElement

public class ExplicitRouteObject
extends PCEPObject

Explicit Route Object The ERO is used to encode the path of a TE LSP through the network. The ERO is carried within a PCRep message to provide the computed TE LSP if the path computation was successful. The contents of this object are identical in encoding to the contents of the Resource Reservation Protocol Traffic Engineering Extensions (RSVP-TE) Explicit Route Object (ERO) defined in [RFC3209], [RFC3473], and [RFC3477]. That is, the object is constructed from a series of sub-objects. Any RSVP-TE ERO sub-object already defined or that could be defined in the future for use in the RSVP-TE ERO is acceptable in this object. PCEP ERO sub-object types correspond to RSVP-TE ERO sub-object types. Since the explicit path is available for immediate signaling by the MPLS or GMPLS control plane, the meanings of all of the sub-objects and fields in this object are identical to those defined for the ERO. ERO Object-Class is 7. ERO Object-Type is 1.
