Using the Area ID to Assign the OSPF Area Number

The OSPF area number is defined in the areaid <IP address> option. The octet format is used in order to be compatible with two different systems of notation used by other OSPF network vendors. There are two valid ways to designate an area ID:

￿Placing the area number in the last octet (0.0.0.n)

Most common OSPF vendors express the area ID number as a single number. For example, the Cisco IOS-based router command “network 1.1.1.0 0.0.0.255 area 1” defines the area number simply as “area 1.” On the G8124, using the last octet in the area ID, “area 1” is equivalent to “area-id 0.0.0.1”.

￿Multi-octet (IP address)

Some OSPF vendors express the area ID number in multi-octet format. For example, “area 2.2.2.2” represents OSPF area 2 and can be specified directly on the G8124 as “area-id 2.2.2.2”.

Note – Although both types of area ID formats are supported, be sure that the area IDs are in the same format throughout an area.

Attaching an Area to a Network

Once an OSPF area has been defined, it must be associated with a network. To attach the area to a network, you must assign the OSPF area index to an IP interface that participates in the area. The format for the command is as follows:

RS G8124(config)# interface ip <interface number>

RS G8124(config-ip-if)# ip ospf area <area index>

RS G8124(config-ip-if)# exit

For example, the following commands could be used to configure IP interface 14 for a presence on the 10.10.10.1/24 network, to define OSPF area 1, and to attach the area to the network:

RS G8124(config)# router ospf

RS G8124(config-router-ospf)# area 1 area-id 0.0.0.1

RS G8124(config-router-ospf)# enable

RS G8124(config-router-ospf)# exit

RS G8124(config)# interface ip 14

RS G8124(config-ip-if)# ip address 10.10.10.1

RS G8124(config-ip-if)#ip netmask 255.255.255.0

RS G8124(config-ip-if)# enable

RS G8124(config-ip-if)# ip ospf area 1

RS G8124(config-ip-if)# ip ospf enable

Note – OSPFv2 supports IPv4 only. IPv6 is supported in OSPFv3 (see “OSPFv3 Implementation in BLADEOS” on page 298).
