Configuring Ospf For A Virtual Link On Switch B - HP GbE2c - Blc Layer 2/3 Fiber SFP Option Application Manual

Configuring OSPF for a virtual link on Switch B

1. Configure IP interfaces on each network that will be attached to OSPF areas.
Two IP interfaces are needed on Switch B: one for the transit area network on 10.10.12.0/24 and one for the
stub area network on 10.10.24.0/24.
>> # /cfg/l3/if 1
>> IP Interface 1 # addr 10.10.12.2
>> IP Interface 1 # mask 255.255.255.0 (Set IP mask
>> IP Interface 1 # enable
>> IP Interface 1 # ../if 2
>> IP Interface 2 # addr 10.10.24.1(Set IP address on stub area network)
>> IP Interface 2 # mask 255.255.255.0(Set IP mask on stub area network)
>> IP Interface 2 # enable
2. Configure the router ID.
A router ID is required when configuring virtual links. This router ID should be the same one specified as the
target virtual neighbor (nbr) on Switch A.
>> IP Interface 2 # /cfg/l3/rtrid 10.10.14.1(Set static router ID)
3. Enable OSPF.
>> IP# /cfg/l3/ospf/on
4. Define the backbone.
This version of GbE2c software requires that a backbone index be configured on the non-backbone end of the
virtual link as follows:
>> Open Shortest Path First # aindex 0(Select the menu for area index 0)
>> OSPF Area (index) 0 # areaid 0.0.0.0(Set the area ID for OSPF area 0)
>> OSPF Area (index) 0 # enable
5. Define the 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. Define the stub area.
>> OSPF Area (index) 1 # ../aindex 2
>> OSPF Area (index) 2 # areaid 0.0.0.2(Set the area ID for OSPF area 2)
>> OSPF Area (index) 2 # type stub
>> OSPF Area (index) 2 # enable
7. Attach the network interface to the backbone.
>> OSPF Area (index) 2 # ../if 1
>> OSPF Interface 1 # aindex 1
>> OSPF Interface 1 # enable
8. Attach the network interface to the transit area.
>> OSPF Interface 1 # ../if 2
>> OSPF Interface 2 # aindex 2
>> OSPF Interface 2 # enable
