Showing OSPF Information

Table 3-6 Field Descriptions for the show ospf lsdb Command (continued)

Field

Description

 

 

ADV Router

This field specifies the OSPF Router ID of the LSA

 

originator, as follows:

 

• ASB-Summary LSAs, the originators are the ABRs

 

• AS-external LSAs, the originators are ASBRs

 

• Network LSAs, the originators are network-designated

 

routers

 

• Router LSAs, this field is identical to the Link State ID

 

field

 

• Summary LSAs, the originators are the ABRs

 

 

Age

The age of the LSA, in seconds. The age is set to 0 when

 

the LSA is originated.

 

 

Sequence

A signed 32-bit integer to detect old and duplicate LSAs.

 

The space of sequence numbers is linearly ordered. The

 

larger the sequence number (when compared as signed

 

32-bit integers), the more recent the LSA.

 

The sequence number 0x80000000 is reserved and unused.

 

 

Checksum

The checksum of the complete contents of the LSA,

 

excluding the age field. The age field is excluded to allow

 

the LSA age to increment without updating the checksum.

 

The checksum is used to detect data corruption of an LSA.

 

This corruption can occur while an LSA is being flooded,

 

or while an LSA is being held in a router’s memory. The

 

LSA checksum field cannot take on the value of zero; the

 

occurrence of this value is a checksum failure.
