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.
