Configure a priority for 
OSPF 

preference [ ase ] [ route-policy 
route-policy-name ] value 

Optional 

The priority of OSPF internal routes 
defaults to 10. 

The priority of OSPF external routes 
defaults to 150. 

 

If the router runs OSPF and other routing protocols, you can configure OSPF to redistribute RIP, IS-IS, 

BGP, static, or direct routes and advertise these routes in Type-5 LSAs or Type-7 LSAs.  

By filtering redistributed routes, OSPF translates only routes not filtered out into Type-5 LSAs or Type-7 

LSAs for advertisement. 

Follow these steps to configure OSPF route redistribution: 

Enter system view 

— 

Enter OSPF view 

ospf [ process-id | router-id router-id | 
vpn-instance instance-name ] *

Configure OSPF  to 
redistribute routes from 
another protocol 

import-route protocol [ process-id | 
all-processes | allow-ibgp ] [ cost cost | 
type type | tag tag | route-policy 
route-policy-name ] * 

Required 

Not configured by 
default. 

Configure OSPF to filter 
redistributed routes before 
advertisement 

filter-policy { acl-number | ip-prefix 
ip-prefix-name } export [ protocol 
[ process-id ] ] 

Optional 

Not configured by 
default. 

 

Only active routes can be redistributed. You can use the display ip routing-table protocol command 

to display route state information. 

 

Using the import-route command cannot redistribute a default external route. To do so, you need to 

use the default-route-advertise command. 

Follow these steps to configure OSPF to redistribute a default external route:
