   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".
