Area-scope LSDB field descriptions
Use the data in the following table to use the Area-scope LSDB tab.
Name | Description |
|---|---|
AreaId | Identifies the area ID from which the LSA is received. Area ID 0.0.0.0 is the OSPF backbone. |
Type | Identifies 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 | Identifies the originating router in the autonomous system. |
Lsid | Identifies 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 | Indicates 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. |
