Configuring Ospf Route Redistribution - HP 6125XLG Configuration Manual

Configuring OSPF route redistribution

On a router running OSPF and other routing protocols, you can configure OSPF to redistribute routes
from other protocols, such as RIP, IS-IS, BGP, static, and direct, and advertise them in Type-5 LSAs or
Type-7 LSAs. In addition, you can configure OSPF to filter redistributed routes so that OSPF advertises
only permitted routes.
IMPORTANT:
The import-route bgp command redistributes only EBGP routes. Because the import-route bgp
allow-ibgp command redistributes both EBGP and IBGP routes, and might cause routing loops, use it with
caution.
Configuring OSPF to redistribute routes from another routing protocol
Step
1. Enter system view.
2. Enter OSPF view.
3. Configure OSPF to
redistribute routes from
another routing protocol.
4. (Optional.) Configure
OSPF to filter redistributed
routes.
Configuring OSPF to redistribute a default route
The import-route command cannot redistribute a default external route. Perform this task to redistribute a
default route.
To redistribute a default route:
Step
1. Enter system view.
2. Enter OSPF view.
3. Redistribute a default
route.

Remarks
N/A
N/A
By default, no route redistribution
is configured.
This command redistributes only
active routes. To view information
about active routes, use the
display ip routing-table protocol
command.
By default, OSPF accepts all
redistributed routes.
Remarks

N/A
By default, no default route is
redistributed.
This command is applicable
only to VPNs. The PE router
advertises a default route in a
Type-3 LSA to a CE router.
