Field Description

Router ID The 32 bit integer in dotted decimal format that uniquely identifies the router

within the autonomous system (AS). The Router ID is set on the OSPFv3

Configuration page. If you want to change the Router ID you must first disable

OSPFv3. After you set the new Router ID, you must re-enable OSPFv3 to

have the change take effect. The default value is 0.0.0.0, although this is not a

valid Router ID.

Area ID The ID of an OSPFv3 area to which one of the router interfaces is connected.

An Area ID is a 32 bit integer in dotted decimal format that uniquely identifies

the area to which an interface is connected.

LSA Type The format and function of the link state advertisement. 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.

LS ID 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.
