One of the following: • Router LSA: A router may originate one or more router-lsas for a given area. Each router-lsa originated in an area describes the collected states of all the router's interfaces to the area. • Network LSA: A network lsa is originated for every link having two or more attached routers, by the designated router. It lists all the routers attached to the link. • Inter-Area Router LSA: This type describes a prefix external to the area, yet internal to the autonomous system. It is originated by an Area Border Router. • AS-External LSA: This LSA type describes a path to a prefix external to the autonomous system and is originated by an Autonomous System Border Router. • Link LSA: A router originates a separate Link-lsa for each attached link. It provides router's link local address to routers attached to the link and also inform them of a list of IPv6 prefixes to associate with the link. • Intra-Area-Prefix LSA: A link's designated router originates one or more intra-area prefix lsas to advertise the link's prefixes throughout the area. A router may originate multiple intra-area-prefix lsas for a given area to advertise its own prefixes and those of its attached stub links. The Link State ID identifies the piece of the routing domain that is being described by the advertisement. The value of the LS ID depends on the advertisement's LS type. Routing 273
