Table 11-8.  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-number options.
