AS-scope LSDB field descriptions
Use the data in the following table to use the AS-scope LSDB tab.
Name | Description |
|---|---|
Type | Shows the type of the link-state advertisement. Each link state type has a separate advertisement format. AS-scope LSAs not recognized by the router may be stored in the database. |
RouterId | Shows the 32 bit number that uniquely identifies the originating router in the autonomous system. |
Lsid | Identifies the piece of the routing domain that is being 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. |
