IP routing configuration examples 149

5530-24TFD(config-router)# as-boundary-router enable 5530-24TFD(config-router)# router-id 1.1.1.3 5530-24TFD(config)# router ospf enable

5Configure OSPF route distribution.

Configure OSPF route distribution to import RIP into OSPF. The Nortel Ethernet Routing Switch 5500 Series distributes the RIP routes as AS-external LSA (LSA type 5), using external metric type 1.

5530-24TFD(config)# router ospf

5530-24TFD(config-router)# redistribute rip enable metric 10 metric-type type1

5530-24TFD(config)# ip ospf apply redistribute rip

6Configure a route policy.

A route policy is required for OSPF to RIP route redistribution. After the route policy is created, apply it to the RIP interface. The following command creates a route policy named allow which distributes both direct and OSPF interfaces.

5530-24TFD(config)# route-map allow permit 1 enable match protocol direct,ospf

7Apply the route policy to the RIP Out Policy.

The following commands apply the route policy created in step 6 to RIP interface 10.1.1.41.

5530-24TFD(config)# interface vlan 100

5530-24TFD(config-if)# ip rip out-policy allow

The configuration steps described in the above example distributes all OSPF routes to RIP. However, there are times when it can be more advantageous to distribute only a default route to RIP. The following configuration steps describe how to distribute only a default route to RIP instead of all OSPF routes to RIP.

To configure R1 to distribute a default route only to RIP, complete the following steps:

Step Action

1Configure an IP prefix list with a default route.

The following command creates an IP prefix list named default with an IP address of 0.0.0.0.

5530-24TFD(config)# ip prefix-list default 0.0.0.0/0
