Displaying OSPF Settings

You can use a number of commands to display settings for OSPF (Open Shortest Path First).

To show global OSPF information, use the show ospf command with no options.
To display information about one or all OSPF areas, enter:

show ospf area {detail | 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 (Virtual LAN), or for all interfaces enter:

show ospf interfaces {vlan vlan-name | area area-identifier | enabled}

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

ExtremeXOS provides several filtering criteria for the show ospf lsdb command.

You can specify multiple search criteria, and only those 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, enter:

show ospf lsdb {detail | stats} {area [area-identifier | all]} {{lstype} [lstype | all]} {lsid lsid-address{lsid-mask}} {routerid routerid-address {routerid-mask}} {interface[[ip-address{ip-mask} | ipNetmask] | vlan vlan-name]}

The detail option displays all fields of matching LSAs in a multiline 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 LSAs from all areas and all types in a summary format.
