Displaying OSPF Settings

There are a number of commands you can use to display settings for OSPF. To show global OSPF

information, use the

show ospf command with no options.

To display information about one or all OSPF areas, use the following command:

show ospf area <area identifier>

The detail option displays information about all OSPF areas in a detail format.

To display information about OSPF interfaces for an area, a VLAN, or for all interfaces, use the

following command:

show ospf interfaces {vlan <vlan name> | area <area identifier>}

The detail option displays information about all OSPF interfaces in a detail format.

OSPF LSDB Display

ExtremeWare provides several filtering criteria for the show ospf lsdb command. You can specify

multiple search criteria and only results matching all of the criteria are displayed. This allows you to

control the displayed entries in large routing tables.

To display the current link-state database, use the following command:

show ospf lsdb area [all | <area identifier>[/<len>] | detail | interface | lsid

<id>[/<len>] | stats | summary | vlan <vlan name>]

The detail option displays all fields of matching LSAs in a multi-line format. The summary option

displays several important fields of matching LSAs, one line per LSA. The

stats option displays the

number of matching LSAs, but not any of their contents. If not specified, the default is to display in the

summary format.

A common use of this command is to omit all optional parameters, resulting in the following shortened

form:

show ospf lsdb

The shortened form displays all areas and all types in a summary format.

Authentication

Authentication is supported at two different levels: interface, and domain or area.
