Output Field What It Displays...
Link ID Link ID, which varies as a function of the link state record type, as follows:
• Net Link States - Shows the interface IP address of the designated router to the
broadcast network.
• Router Link States - Shows the ID of the router originating the record.
• Summary Link States - Shows the summary network prefix.
ADV Router Router ID of the router originating the link state record.
Age Age (in seconds) of the link state record.
Seq# OSPF sequence number assigned to each link state record.
Checksum Field in the link state record used to verify the contents upon receipt by another
router.
LinkCount Link count of router link state records. This number is equal to, or greater than, the
number of active OSPF interfaces on the originating router.
