• Inter-Area-Router LSA—Type-4 LSA, originated by ABRs and flooded throughout the LSA's
associated area. Each Inter-Area-Router LSA describes a route to ASBR.
• AS External LSA—Type-5 LSA, originated by ASBRs, and flooded throughout the AS, except stub
areas and Not-So-Stubby Areas (NSSAs). Each AS External LSA describes a route to another AS. A
default route can be described by an AS External LSA.
• NSSA LSA—Type-7 LSA, originated by ASBRs in NSSAs and flooded throughout a single NSSA.
NSSA LSAs describe routes to other ASs.
• Link LSA—Type-8 LSA. A router originates a separate Link LSA for each attached link. Link LSAs
have link-local flooding scope. Each Link LSA describes the IPv6 address prefix of the link and
Link-local address of the router.
• Intra-Area-Prefix LSA—Type-9 LSA. Each Intra-Area-Prefix LSA contains IPv6 prefix information on
a router, stub area, or transit area information, and has area flooding scope. It was introduced
because Router LSAs and Network LSAs contain no address information.
• Grace LSA—Type-11 LSA, generated by a GR restarter at reboot and transmitted on the local link.
The GR restarter describes the cause and interval of the reboot in the Grace LSA to notify its
neighbors that it performs a GR operation.
