route-policy-name: Rout policy name, a string of 1 to 19 characters.

value: Priority value, in the range 1 to 255. A smaller value has a higher priority.

Use the preference command to set the priority of OSPF routes.

Use the undo preference command to restore the default.

The priority of OSPF internal routes defaults to 10, and the priority of OSPF 
external routes defaults to 150.

If a routing policy is specified, priorities defined by the routing policy will apply to 
matched routes, and the priorities set with the preference command apply to 
OSPF routes not matching the routing policy.

A router may run multiple routing protocols. When several routing protocols find 
routes to the same destination, the router uses the route found by the protocol 
with the highest priority.

process-id: OSPF process ID, in the range 1 to 65535.

neighbor: Clears neighbor statistics on an interface.

interface-type interface-number: Interface type and interface number.

router-id: Neighbor router ID.

Use the reset ospf counters command to reset OSPF counters. If no OSPF 
process is specified, counters of all OSPF processes are reset.
