Description

OSPFv3 Link-State Advertisement
OSPFv3 packets use protocol ID 89, and routers communicate
with each other using the local interface’s IPv6 link-local
address. The OSPF link-state database information is organized
and advertised differently in Version 3 than in Version 2.
OSPFv3 modifies the structure of the router LSA (type 1),
renames the network summary LSA to the interarea prefix LSA,
and renames the ASBR summary LSA to the interarea router
LSA. The principal difference is that the router LSA is only
responsible for announcing interface parameters such as the
interface type (point-to-point, broadcast, NBMA, point-tomultipoint, and virtual links) and metric (cost).
IP address information is advertised independently by two new
LSA types:
Intra-area prefix LSA
Link-local LSA
