Non-Configurable Data
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 Interface 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 Links

Network Links

Network Summary

ASBR Summary


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.
Age - The time since the link state advertisement was first originated, in seconds.
Sequence - The sequence number field is a signed 32-bit integer. It is used to detect old and
duplicate link state advertisements. The larger the sequence number, the more recent the
advertisement.
Checksum - The checksum is used to detect data corruption of an advertisement. This corruption
can occur while an advertisement is being flooded, or while it is being held in a router's memory. This
field is the checksum of the complete contents of the advertisement, except the LS age field.
Options - The Options field in the link state advertisement header indicates which optional
capabilities are associated with the advertisement.
Rtr Options - The router specific options.
