View 
OSPF view 
Default Level 
2: System level 
Parameters 
ase: Sets a priority for ASE routes. If the keyword is not specified, using the command sets a priority for 
OSPF internal routes. 
route-policy  route-policy-name: Applies a route policy to set priorities for specified routes. 
route-policy-name is a string of 1 to 19 characters. 
value: Priority value, in the range 1 to 255. A smaller value represents a higher priority. 
Description 
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 route policy is specified, priorities defined by the route policy will apply to matching routes, and the 
priorities set with the preference command apply to OSPF routes not matching the route 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. 
Examples 
# Set a priority of 200 for OSPF external routes. 
<Sysname> system-view 
[Sysname] ospf 100 
[Sysname-ospf-100] preference ase 200
