Displaying OSPF information
6
Syntax: show ip ospf database external-link-state [advertise num] | [extensive] | [link-state-id
ip-addr] | [router-id ip-addr] | [sequence-number num(Hex)] | [status num]
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 database external-link-state command
to display the table. Refer to
“Displaying the data in an LSA” on page 147 for an example.
The extensive option displays the LSAs in decrypted format.
NOTE
You cannot use the extensive option in combination with other display options. The entire database
is displayed.
The link-state-id ip-addr parameter displays the External LSAs for the LSA source specified by
IP-addr.
The router-id ip-addr parameter shows the External LSAs for the specified OSPF router.
The sequence-number num(Hex) parameter displays the External LSA entries for the specified
hexadecimal LSA sequence number.
The status num option shows status information.
This display shows the following information.
TABLE 18 CLI display of OSPF external link state information
This field... Displays...
Area ID The OSPF area the router is in.
Aging The age of the LSA, in seconds.
LS ID The ID of the link-state advertisement from which the Layer 3 Switch learned
this route.
Router The router IP address.
Seq(hex) The sequence number of the LSA. The OSPF neighbor that sent the LSA stamps
it with a sequence number to enable the Layer 3 Switch and other OSPF
routers to determine which LSA for a given route is the most recent.
Chksum A checksum for the LSA packet. The checksum is based on all the fields in the
packet except the age field. The Layer 3 Switch uses the checksum to verify
that the packet is not corrupted.
Type The route type, which is always EXTR (external).
