6. Optionally configure route summarization between OSPF areas.
7. Optionally configure virtual links.
8. Optionally configure host routes.
Example 1: Simple OSPF Domain
In this example, two OSPF areas are defined: the backbone and the stub area. A stub area does not
allow advertisements of external routes, thus reducing the size of the database. Instead, a default
summary route of IP address 0.0.0.0 is inserted into the stub area. Any traffic for IP address
destinations outside the stub area is forwarded to the stub area's IP interface, and then into the
backbone.
Figure 21: Simple OSPF Domain Example
1. Configure IP interfaces on each network that is attached to OSPF areas.
Two IP interfaces are needed: one for the backbone network on 10.10.7.0/24, and one for the
stub area network on 10.10.12.0/24.
>> # /cfg/l3/if 1
>> IP Interface 1 # addr 10.10.7.1
>> IP Interface 1 # mask 255.255.255.0
>> IP Interface 1 # enable
>> IP Interface 1 # /cfg/l3/if 2
>> IP Interface 2 # addr 10.10.12.1
>> IP Interface 2 # mask 255.255.255.0
>> IP Interface 2 # enable
2. Enable OSPF.
>> IP Interface 2 # /cfg/l3/ospf/on
3. Define the backbone. Always configure the backbone as a transit area using
