Configuring OSPF

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 routing switch, use one of the following methods.

USING THE CLI

To display external link state information, enter the following command at any CLI level:

HP9300> show ip ospf database external-link-state

Ospf ext link-state by router ID 130.130.130.241 are in the following:

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 routing switch’s External LSA table. To determine an LSA packet’s position in the table, enter the show ip ospf external-link-statecommand to display the table. See “Displaying the Data in an LSA” on page 8-46for 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.

 

Table 8.5: 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 routing 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 routing 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 routing switch uses the

 

 

checksum to verify that the packet is not corrupted.

 

 

 

Type

 

The route type, which is always EXTR (external).
