Abstract Abstract
OSPFv3 requires functional extension beyond what can readily be done OSPFv3 requires functional extension beyond what can readily be done
with the fixed-format Link State Advertisement (LSA) as described in with the fixed-format Link State Advertisement (LSA) as described in
RFC 5340. Without LSA extension, attributes associated with OSPFv3 RFC 5340. Without LSA extension, attributes associated with OSPFv3
links and advertised IPv6 prefixes must be advertised in separate links and advertised IPv6 prefixes must be advertised in separate
LSAs and correlated to the fixed-format LSAs. This document extends LSAs and correlated to the fixed-format LSAs. This document extends
the LSA format by encoding the existing OSPFv3 LSA information in the LSA format by encoding the existing OSPFv3 LSA information in
Type-Length-Value (TLV) tuples and allowing advertisement of Type-Length-Value (TLV) tuples and allowing advertisement of
