IPv6 OSPF v3 LSA Types

Link State Type field is 16 bits rather than 8 with IPv4.

 

 OSPFv3 removes the prefix advertisement function from router and network LSAs and puts it in the new Intra-Area Prefix LSA and Link LSA

The Router LSA - OSPFv3

This only describes the originating router and it's links to its neighbors. Prefix information is carried in the intra-area prefix LSA

The Network LSA - OSPFv3

Functionally it is identical to the OSPFv2 Network (Type 2 LSA)

The Inter-Area Prefix LSA - OSPFv3

Functionally it is identical to the OSPFv2 Summary (Type 3 LSA)

The Inter-Area Router - OSPFv3

Functionally it is identical to the OSPFv2 ASBR Summary (Type 4 LSA)

 The AS-External LSA - OSPFv3

Functionally it is identical to the OSPFv2 AS External (Type 5 LSA) except for:

The Link LSA - OSPFv3

The link LSA is used for communicating information that is significant only to two directly connected neighbors. A separate link LSA is originated on each if a routers attached links belonging to an OSPFv3 domain.
