Showing OSPF Information
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.
