TABLE 63

This field Displays

Index

ID of the entry

Area ID

ID of the OSPF area

Type

Link state type of the route.

LS ID

The ID of the link-state advertisement from which the router learned this route.

Adv Rtr

ID of the advertised route.

Seq(Hex) The sequence number of the LSA. The OSPF neighbor that sent the LSA stamps the LSA with a

sequence number. This number enables the device and other OSPF routers to determine which LSA
for a given route is the most recent.

Age

The age of the LSA in seconds.

Chksum

The checksum for the LSA packet. The checksum is based on all the fields in the packet except the
age field. The device uses the checksum to verify that the packet is not corrupted.

SyncState This field indicates whether the synchronization is complete or not.

Syntax: show ip ospf database external-link-state [ advertise num | extensive | link-state-id ip-
addr
| router-id ip-addr | sequence-number num(Hex) ]

The advertise num parameter displays the hexadecimal data in the specified LSA packet. The num
parameter identifies the LSA packet by its position in the router’s External LSA table. To determine an
LSA packet’s position in the table, enter the show ip ospf external-link-state command to display the
table.
