Clearing OSPF information 29 • OSPF area information, including routes received from OSPF neighbors within an area, as well as routes imported into the area. You can clear area information for all OSPF areas, or for a specified OSPF area The OSPF information is cleared dynamically when you enter the command; you do not need to remove statements from the Dell PowerConnect configuration or reload the software for the change to take effect. Clearing OSPF neighbor information To clear information on the Dell PowerConnect device about all OSPF neighbors, enter the following command. PowerConnect#clear ip ospf neighbor Syntax: clear ip ospf neighbor [ip | id ] This command clears all OSPF neighbors and the OSPF routes exchanged with the neighbors in the Dell PowerConnect OSPF link state database. After this information is cleared, adjacencies with all neighbors are re-established, and routes with these neighbors exchanged again. To clear information on the Dell PowerConnect device about OSPF neighbor 10.10.10.1, enter the following command. PowerConnect#clear ip ospf neighbor ip 10.10.10.1 This command clears the OSPF neighbor and the OSPF routes exchanged with neighbor 10.10.10.1 in the OSPF link state database in the Dell PowerConnect device. After this information is cleared, the adjacency with the neighbor is re-established, and routes are exchanged again. The neighbor router can be specified either by its IP address or its router ID. To specify the neighbor router using its IP address, use the ip parameter. To specify the neighbor router using its router ID, use the id parameter. Clearing OSPF topology information To clear OSPF topology information on the Dell PowerConnect device, enter the following command. PowerConnect#clear ip ospf topology Syntax: clear ip ospf topology This command clears all OSPF routes from the OSPF routing table, including intra-area, (which includes ABR and ASBR intra-area routes), inter-area, external type 1, external type 2, OSPF default, and OSPF summary routes. After you enter this command, the OSPF routing table is rebuilt, and valid routes are recomputed from the OSPF link state database. When the OSPF routing table is cleared, OSPF routes in the global routing table are also recalculated. If redistribution is enabled, the routes are imported again. Clearing redistributed routes from the OSPF routing table To clear all routes in the OSPF routing table that were redistributed from other protocols, enter the following command.
