RFC 1587 — The OSPF NSSA Option

Enabling OSPF

To enable OSPF, create the OSPF routing process, specify the range of IP addresses

associated with the routing process, and assign the area IDs associated with that range

of IP addresses.

To create the OSPF routing process, perform the following steps:

1. To enable OSPF routing, use the router ospf command in Global Configuration

mode, as shown below:

MOT(config)#router ospf

This enables OSPF routing and places you in Router Configuration mode.

2. To define an OSPF interface and define its area ID, use the network area

command in Router Configuration mode, as shown below:

MOT(config-ospf)#network <ip-address> <mask> area <area-id>

where:

ip-address is the IP address of the OSPF network.

mask is the IP address type mask with don’t care bits (wildcard mask).

area-id is the network area ID, OSPF address range, either decimal value or

IP address. If areas are associated with IP subnets, subnet area may be

specified.

Example

The following example creates the OSPF routing process and adds two OSPF ranges

(3.3.3.0/24 and 3.3.3.0/24) with each range belonging to a different area. Area 0 is

configured for 3.3.3.0/24 and Area 1 is configured for 3.3.3.0/24.The example creates

two OSPF interfaces. One interface is in the backbone area (Area 0) using IP address

3.3.3.1. The other interface is in the non-backbone area (Area 1) using IP address

3.3.3.1.

ip address 3.3.3.1 255.255.255.0
