Using the Area ID to Assign the OSPF Area Number
The OSPF area number is defined in the
order to be compatible with two different notation systems 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
using the last octet in the area ID, area 1 is equivalent to areaid 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 in
Alteon as areaid 2.2.2.2.
Note: Although both types of area ID formats are supported, ensure 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:
>> # /cfg/l3/ospf/if <interface number> /aindex <area index>
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:
>> # /cfg/l3/if 14
>> IP Interface 14# addr 10.10.10.1
>> IP Interface 14# mask 255.255.255.0
>> IP Interface 14# ena
>> IP Interface 14# /cfg/l3/ospf/aindex 1
>> OSPF Area (index) 1 # areaid 0.0.0.1
>> OSPF Area (index) 1 # ena
>> OSPF Area (index) 1 # /cfg/l3/ospf/if 14
