OSPFv3 requires functional extension beyond what can readily be done
with the fixed-format Link State Advertisement (LSA) as described in
RFC 5340. Without LSA extension, attributes associated with OSPFv3
links and advertised IPv6 prefixes must be advertised in separate
LSAs and correlated to the fixed-format LSAs. This document extends
the LSA format by encoding the existing OSPFv3 LSA information in
Type-Length-Value (TLV) tuples and allowing advertisement of
additional information with additional TLVs. Backward-compatibility
mechanisms are also described.
This document updates RFC 5340, "OSPF for IPv6", and RFC 5838,
"Support of Address Families in OSPFv3", by providing TLV-based
encodings for the base OSPFv3 unicast support and OSPFv3 address
family support.
This document is a product of the Open Shortest Path First IGP Working Group of the IETF.
This is now a Proposed Standard.
