Open Shortest Path First (OSPF)
>> OSPF Area (index) 1 # type stub
>> OSPF Area (index) 1 # enable
5. Attach the network interface to the backbone.
>> OSPF Area (index) 1 # /cfg/l3/ospf/if 1
>> OSPF Interface 1 # aindex 0
>> OSPF Interface 1 # enable
6. Attach the network interface to the stub area.
>> OSPF Interface 1 # /cfg/l3/ospf/if 2
>> OSPF Interface 2 # aindex
>> OSPF Interface 2 # enable
7. Configure route summarization by specifying the starting address and mask of the range of
addresses to be summarized
>> OSPF Interface 2 # /cfg/l3/ospf/range 1
>> OSPF Summary Range 1 # addr 36.128.192.0
>> OSPF Summary Range 1 # mask 255.255.192.0
>> OSPF Summary Range 1 # aindex 0
>> OSPF Summary Range 1 # enable
8. Use the hide command to prevent a range of addresses from advertising to the backbone.
>> OSPF Interface 2 # /cfg/l3/ospf/range 2
>> OSPF Summary Range 2 # addr 36.128.200.0
>> OSPF Summary Range 2 # mask 255.255.255.0
>> OSPF Summary Range 2 # hide enable
9. Apply and save the configuration changes.
>> OSPF Summary Range 2 # apply
>> OSPF Summary Range 2 # save
Example 4: Host Routes
The Alteon OSPF implementation includes host routes. Host routes are used for advertising network
device IP addresses to external networks and allows for Server Load Balancing (SLB) within OSPF. It
also makes ABR load sharing and failover possible.

content and are configured with the same virtual server IP addresses: 10.10.10.1 and 10.10.10.2.
Alteon 1 is given a host route with a low cost for virtual server 10.10.10.1, and another host route
with a high cost for virtual server 10.10.10.2. Alteon 2 is configured with the same hosts but with
the costs reversed; one host route has a high cost for virtual server 10.10.10.1, and another has a
low cost for virtual server 10.10.10.2.
