The output includes the following fields:
Displaying OSPF link-state advertisements
To display additional information about an LSA in the link-state database, first display the
database as described in the preceding section. Then specify an LSA to expand. Use the
following format:
show ospf lsa area ls-type ls-id adv-rtr
This command requires that you include the first four fields of the LSA as listed in the
database. You can select the first four fields and paste them in after typing the command. For
Field Description
Area field Area ID.
LS Type Type of link as defined in RFC 1583:
Type 1 (RTR) are router-LSAs that describe the collected states of the
router’s interfaces.
Type 2 (NET) are network-LSAs that describe the set of routers attached to
the network.
Types 3 and 4 (STUB) are summary-LSAs that describe point-to-point
routes to networks or AS boundary routers.
Type 5 (ASE) are AS-external-LSAs that describe routes to destinations
external to the Autonomous System. A default route for the Autonomous
System can also be described by an AS-external-LSA.
Link ID Target address of the route.
Adv Rtr Address of the advertising router.
Age Age of the route in seconds.
Len Length of the LSA.
Seq # Number that begins with 80000000 and increments by one for each LSA
received.
Metric Cost of the link, not of a route. The cost of a route is the sum of all
intervening links, including the cost of the connected route.
