About this task

View the area-scope LSDB to see the LSAs that are flooded in a single OSPFv3 area. Area scope is used in router LSAs, network LSAs, Inter-Area-Prefix-LSAs, Inter-Area-Router LSAs, and Intra-Area-Prefix-LSAs.

Area-scope LSDB Field Descriptions

Use the data in the following table to use the Area-scope LSDB tab.

Name

Description

AreaId

Specifies the area ID from which the LSA is received. Area ID 0.0.0.0 is the OSPF backbone.

Type

Specifies the type of the link-state advertisement. Each link-state type has a separate advertisement format. Area-scope LSAs unrecognized by the router are also stored in this database.

RouterId

Specifies the originating router in the autonomous system.

Lsid

Specifies the piece of the routing domain that is described by the advertisement.

Sequence

Shows a signed 32-bit integer that detects old and duplicate link-state advertisements. The larger the sequence number, the more recent the advertisement.

Age

Shows the age of the link-state advertisement in seconds.

Checksum

Specifies the checksum of the complete contents of the advertisement, except the age field. The age field is not affected so that the advertisement age value increments without updating the checksum. The checksum used is the same for ISO connectionless datagrams, the Fletcher checksum.
