Figure 23 Summarizing routes
NOTE:
You can specify a range of addresses to prevent advertising by using the hide option. In
this example, routes in the range 36.128.200.0 through 36.128.200.255 are kept private.
Follow this procedure to configure OSPF support on Switch A and Switch B, as shown in the figure.
1.
Configure IP interfaces for each network which will be attached to OSPF areas.
>> # /cfg/l3/if 1(Select menu for IP interface 1)
>> IP Interface 1 # addr 10.10.7.1(Set IP address on backbone network)
>> IP Interface 1 # mask 255.255.255.0(Set IP mask on backbone network)
>> IP Interface 1 # ena(Enable IP interface 1)
>> IP Interface 1 # ../if 2(Select menu for IP interface 2)
>> IP Interface 2 # addr 36.128.192.1(Set IP address on stub area network)
>> IP Interface 2 # mask 255.255.192.0(Set IP mask on stub area network)
>> IP Interface 2 # ena(Enable IP interface 2)
2. Enable OSPF.
>> IP Interface 2 # /cfg/l3/ospf/on
3. Define the backbone.
>> Open Shortest Path First # aindex 0 (Select menu for area index 0)
>> OSPF Area (index) 0 # areaid 0.0.0.0(Set the ID for backbone area 0)
>> OSPF Area (index) 0 # type transit
>> OSPF Area (index) 0 # enable
4. Define the stub area.
>> OSPF Area (index) 0 # ../aindex 1
>> OSPF Area (index) 1 # areaid 0.0.0.1 (Set the area ID for OSPF
>> OSPF Area (index) 1 # type stub
>> OSPF Area (index) 1 # enable
5.
Attach the network interface to the backbone.
>> OSPF Area (index) 1 # ../if 1
>> OSPF Interface 1 # aindex 0
>> OSPF Interface 1 # enable
6.
Attach the network interface to the stub area.
>> OSPF Interface 1 # ../if 2
>> OSPF Interface 2 # aindex 1
>> OSPF Interface 2 # enable
(Define backbone as transit type)
(Enable the area)
(Select menu for area index 1)
area 1)
(Define area as stub type)
(Enable the area)
(Select OSPF menu for IP interface 1)
(Attach network to backbone index)
(Enable the backbone interface)
(Select OSPF menu for IP interface 2)
(Attach network to stub area index)
(Enable the stub area interface)
