link-state-id	(OPTIONAL) Specify LSA ID in dotted decimal format. The LSA ID value depends on the LSA type, and it can be one of the following: the network’s IP address for Type 3 LSAs or Type 5 LSAs the router’s OSPF router ID for Type 1 LSAs or Type 4 LSAs the default destination (0.0.0.0) for Type 5 LSAs
adv-router ip-address	(OPTIONAL) Enter the keywords `adv-router` and the ip-address to display only the LSA information about that router.

Field	Description
LS Age	Displays the LSA’s age.
Options	Displays the optional capabilities available on router. The following options can be found in this item: TOS-capability or No TOS-capability is displayed depending on whether the router can support Type of Service. DC or No DC is displayed depending on whether the originating router can support OSPF over demand circuits. E or No E is displayed on whether the originating router can accept AS External LSAs.
LS Type	Displays the LSA’s type.
Link State ID	Displays the Link State ID.
Advertising Router	Identifies the router ID of the LSA’s originating router.
LS Seq Number	Identifies the link state sequence number. This number enables you to identify old or duplicate LSAs.
Checksum	Displays the Fletcher checksum of the LSA’s complete contents.
Length	Displays the length in bytes of the LSA.
Network Mask	Displays the network mask implemented on the area.
Metrics Type	Displays the external type.
TOS	Displays the Type of Service (TOS) options. Option 0 is the only option.
Metric	Displays the LSA metric.
Forward Address	Identifies the address of the forwarding router. Data traffic is forwarded to this router. If the forwarding address is 0.0.0.0, data traffic is forwarded to the originating router.
External Route Tag	Displays the 32-bit field attached to each external route. The OSPF protocol does not use this field, but you can use the field for external route management.
