Class InterASTEv2LSA

java.lang.Object

es.tid.ospf.ospfv2.lsa.LSA

es.tid.ospf.ospfv2.lsa.OpaqueLSA

es.tid.ospf.ospfv2.lsa.InterASTEv2LSA

public class InterASTEv2LSA
extends OpaqueLSA

Represents a Inter AS TE v2 LSA, see RFC 5392.

For the advertisement of OSPFv2 inter-AS TE links, a new Opaque LSA, the Inter-AS-TE-v2 LSA, is defined in this document. The Inter-AS-TE-v2 LSA has the same format as "Traffic Engineering LSA", which is defined in [OSPF-TE].

The inter-AS TE link advertisement SHOULD be carried in a Type 10 Opaque LSA [RFC5250] if the flooding scope is to be limited to within the single IGP area to which the ASBR belongs, or MAY be carried in a Type 11 Opaque LSA [RFC5250] if the information is intended to reach all routers (including area border routers, ASBRs, and PCEs) in the AS. The choice between the use of a Type 10 (area-scoped) or Type 11 (AS-scoped) Opaque LSA is an AS-wide policy choice, and configuration control of it SHOULD be provided in ASBR implementations that support the advertisement of inter-AS TE links.

The Link State ID of an Opaque LSA as defined in [RFC5250] is divided into two parts. One of them is the Opaque type (8-bit), the other is the Opaque ID (24-bit). The value for the Opaque type of Inter-AS-TE-v2 LSA is 6 and has been assigned by IANA (see Section 6.1). The Opaque ID of the Inter-AS-TE-v2 LSA is an arbitrary value used to uniquely identify Traffic Engineering LSAs. The Link State ID has no topological significance.

The TLVs within the body of an Inter-AS-TE-v2 LSA have the same format as used in OSPF-TE. The payload of the TLVs consists of one or more nested Type/Length/Value triplets. New sub-TLVs specifically for inter-AS TE Link advertisement are described in Section 3.2.
