HP GbE2c - Blc Layer 2/3 Fiber SFP Option Application Manual page 125

In this example, two IP interfaces are needed on Switch A: one for the backbone network on 10.10.7.0/24
and one for the transit 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 (Set IP mask on backbone network)
>> IP Interface 1 # enable
>> IP Interface 1 # ../if 2
>> IP Interface 2 # addr 10.10.12.1 (Set IP address on
>> IP Interface 2 # mask 255.255.255.0 (Set IP mask on
>> IP Interface 2 # enable
2. Configure the router ID.
A router ID is required when configuring virtual links. Later, when configuring the other end of the virtual link on
Switch B, the router ID specified here will be used as the target virtual neighbor (nbr) address
>> IP Interface 2 # /cfg/l3/rtrid 10.10.10.1
3. Enable OSPF.
>> IP # /cfg/l3/ospf/on
4. Define the backbone.
>> Open Shortest Path First # aindex 0
>> OSPF Area (index) 0 # areaid 0.0.0.0
>> OSPF Area (index) 0 # type transit
>> OSPF Area (index) 0 # enable
5. Define the transit area.
The area that contains the virtual link must be configured as a transit area
>> OSPF Area (index) 0 # ../aindex 1
>> OSPF Area (index) 1 # areaid 0.0.0.1(Set the area ID for OSPF area 1)
>> OSPF Area (index) 1 # type transit
>> OSPF Area (index) 1 # enable
6. Attach the network interface to the backbone.
>> OSPF Area (index) 1 # ../if 1
>> OSPF Interface 1 # aindex 0
>> OSPF Interface 1 # enable
7. Attach the network interface to the transit area.
>> OSPF Interface 1 # ../if 2
>> OSPF Interface 2 # aindex 1
>> OSPF Interface 2 # enable
8. Configure the virtual link.
The nbr router ID configured in this step must be the same as the router ID that will be configured for Switch B
in step 2.
>> OSPF Interface 2 # ../virt 1
>> OSPF Virtual Link 1 # aindex 1
>> OSPF Virtual Link 1 # nbr 10.10.14.1 (Specify the router ID
>> OSPF Virtual Link 1 # enable
9. Apply and save the configuration changes
>> OSPF Interface 2 # apply
>> OSPF Interface 2 # save
