+.. index:: clear ip ospf [(1-65535)] process
+.. clicmd:: clear ip ospf [(1-65535)] process
+
+ This command can be used to clear the ospf process data structures. This
+ will clear the ospf neighborship as well and it will get re-established.
+ This will clear the LSDB too. This will be helpful when there is a change
+ in router-id and if user wants the router-id change to take effect, user can
+ use this cli instead of restarting the ospfd daemon.

+.. index:: clear ip ospf [(1-65535)] neighbor
+.. clicmd:: clear ip ospf [(1-65535)] neighbor
+
+ This command can be used to clear the ospf neighbor data structures. This
+ will clear the ospf neighborship and it will get re-established. This
+ command can be used when the neighbor state get stuck at some state and
+ this can be used to recover it from that state.
