configuration panel is displayed.
2. Click on the plus sign next to Monitor in the tree view to expand the list of monitoring options.

4. Click on the External Link State DB link.

Displaying OSPF Link State Information

To display link state information for the router, use one of the following methods.
USING THE CLI
To display link state information, enter the following command at any CLI level:
BigIron> show ip ospf database link-state
Syntax: show ip ospf database link-state [advertise <num>] | [link-state-id <ip-addr>] | [network] | [router] |
[router-id <ip-addr>] | [sequence-number <num(Hex)>] | [status <num>] [summary]
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. See
"Displaying the Data in an LSA" on page 17-49 for an example.
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.

Displaying the Data in an LSA

You can use the CLI to display the data the Layer 3 Switch received in a specific External LSA packet or other type
of LSA packet. For example, to display the LSA data in entry 3 in the External LSA table, enter the following
command:
BigIron> show ip ospf database external-link-state advertise 3
05 84 02 05 82 83 0d 60 82 82 82 f1 80 00 00 02 e4 05
00 24 ff ff ff f0 80 00 00 0a 00 00 00 00 00 00 00 00
Syntax: show ip ospf database external-link-state [advertise <num>] | [link-state-id <ip-addr>] |
[router-id <ip-addr>] | [sequence-number <num(Hex)>] | [status <num>]
To determine an external LSA's or other type of LSA's index number, enter one of the following commands to
display the appropriate LSA table:
• show ip ospf database link-state advertise <num> – This command displays the data in the packet for the
specified LSA.
• show ip ospf database external-link-state advertise <num> – This command displays the data in the
packet for the specified external LSA.
