public class RRO
extends RSVPObject

RFC 3209 RSVP-TE Record Route Object

Routes can be recorded via the RECORD_ROUTE object (RRO). Optionally, labels may also be recorded. The Record Route Class is 21. Currently one C_Type is defined, Type 1 Record Route. The RECORD_ROUTE object has the following format: Class = 21, C_Type = 1 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | // (Subobjects) // | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Subobjects The contents of a RECORD_ROUTE object are a series of variable-length data items called subobjects. The subobjects are defined in section 4.4.1 below. The RRO can be present in both RSVP Path and Resv messages. If a Path message contains multiple RROs, only the first RRO is meaningful. Subsequent RROs SHOULD be ignored and SHOULD NOT be propagated. Similarly, if in a Resv message multiple RROs are encountered following a FILTER_SPEC before another FILTER_SPEC is encountered, only the first RRO is meaningful. Subsequent RROs SHOULD be ignored and SHOULD NOT be propagated.
