Table 3-5 Field Descriptions for show ospf interfaces Command (continued)

Field

Description

 

 

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.

 

 

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
