Syntax: clear ospf redistribution
This command clears all routes in the OSPF routing table that are redistributed from other
protocols, including direct connected, static, RIP, and BGP. To import redistributed routes from
other protocols, use the redistribution command at the OSPF configuration level.

Clearing information for OSPF areas

To clear information on the Dell PowerConnect device about all OSPF areas, enter the following
command.
PowerConnect#clear ip ospf
This command clears all OSPF areas, all OSPF neighbors, and the entire OSPF routing table. After
this information has been cleared, adjacencies with all neighbors are re-established, and all OSPF
routes are re-learned.
To clear information on the Dell PowerConnect device about OSPF area 1, enter the following
command.
PowerConnect#clear ip ospf area 1
This command clears information about the specified area ID. Information about other OSPF areas
is not affected. The command clears information about all OSPF neighbors belonging to the
specified area, as well as all routes imported into the specified area. Adjacencies with neighbors
belonging to the area are re-established, and routes imported into the area are re-learned.
Syntax: clear ip ospf [area <area-id>]
The <area-id> can be specified in decimal format or in IP address format.
