Displaying Ospf External Link State Information - Foundry Networks Switch and Router Installation And Configuration Manual

USING THE WEB MANAGEMENT INTERFACE
You cannot display the OSPF route table using the Web management interface.

Displaying OSPF External Link State Information

To display external link state information for the router, use one of the following methods.
USING THE CLI
To display external link state information, enter the following command at any CLI level:
BigIron> show ip ospf database external-link-state
Ospf ext link-state by router ID 130.130.130.241 are in the following:
Area ID
0.0.0.0
0.0.0.0
0.0.0.0
0.0.0.0
0.0.0.0
0.0.0.0
0.0.0.0
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>]
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.
This display shows the following information.

The OSPF area the router is in.
The age of the LSA, in seconds.
The ID of the link-state advertisement from which the Layer 3 Switch
learned this route.
The router IP address.
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.
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.
The route type, which is always EXTR (external).
