Syntax: show ip ospf external-link-state

The OSPF external link state display shows the following information:

Table 16-5. CLI Display of OSPF External Link State Information

This Field...

Displays...

 

 

Link State ID

LSA ID for this LSA. Normally, the destination of the external route,

 

but may have some “host” bits set.

 

 

Router ID

Router ID of the router that originated this external LSA.

 

 

Age

Current age (in seconds) of this LSA.

 

 

Sequence #

Sequence number of the current instance of this LSA.

 

 

Chksum(Hex)

LSA checksum value.

 

 

Syntax: show ip ospf external-link-state [status advertise] [link-state-id <link- state-id> router-id <router-id> sequence-number <sequence#>]

The status keyword is optional and can be omitted. The output can be filtered to show a subset of the total output by specifying the link-state-id, router-id, or sequence-numberoptions.

The advertise keyword displays the hexadecimal data in the specified LSA packet, the actual contents of the LSAs. This can also be filtered as above by including the link-state-id, router-id, or sequence-numberoptions.
