Configuring Ospf Route Redistribution - H3C LS-3100-52P-OVS-H3 Operation Manual

Configuring OSPF Route Redistribution

Configure route redistribution into OSPF
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:
To do...
Enter system view
Enter OSPF view
Configure OSPF to
redistribute routes from
another protocol
Configure OSPF to filter
redistributed routes before
advertisement
Only active routes can be redistributed. You can use the display ip routing-table protocol command
to display route state information.
Configure OSPF to redistribute a default route
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:
To do...
Enter system view
Enter OSPF view
Redistribute a default route
Use the command...
system-view
ospf [ process-id | router-id router-id |
vpn-instance instance-name ] *
import-route protocol [ process-id |
all-processes | allow-ibgp ] [ cost cost |
type type | tag tag | route-policy
route-policy-name ] *
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [ protocol
[ process-id ] ]
Use the command...
system-view
ospf [ process-id | router-id router-id |
vpn-instance instance-name ] *
default-route-advertise [ always | cost cost |
type type | route-policy route-policy-name ] *
default-route-advertise summary cost cost
