Showing Link-State Databases
You can show the entire OSPF link-state database (LSDB) or its specific entry
types with the show ospf lsdb command. The options for the show ospf lsdb
command are as follows:
•show ospf lsdb router - Displays router LSAs that describe the states of the
router interfaces
•show ospf lsdb network - Displays network LSAs that describe the set of
routers attached to the network
•show ospf lsdb external - Displays AS-external LSAs that describe routes to
destinations external to the AS
•show ospf lsdb summary - Displays summary LSAs that describe
summarized routes to the network
•show ospf lsdb asbr_summ - Displays summary LSAs that describe routes
to AS boundary routers
Transit Delay The number of seconds to transmit a Link State Update
packet over an interface. LSAs contained in the Link State
Update packet have their age incremented by this amount
before transmission. This value should take into account
transmission and propagation delays; the value must be
greater than zero.
Retransmit The number of seconds between LSA retransmissions for
adjacencies belonging to an interface. Also, the interval is
used when retransmitting Database Description and Link
State Request packets.
Cost The cost of sending a data packet on the interface,
expressed in the link-state metric. The cost of sending a
packet is advertised as the link cost for the interface in the
router LSA. The cost of an interface must be greater than
zero.
