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 (Select menu for IP interface 1) >> IP Interface 1 # addr 10.10.12.2 (Set IP address on transit area network) >> IP Interface 1 # mask 255.255.255.0 (Set IP mask on transit area network) >> IP Interface 1 # enable (Enable IP interface 1) >> IP Interface 1 # ../if 2 (Select menu for IP interface 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 (Enable IP interface 2) 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 (Enable the area) 5. Define the transit area. >> OSPF Area (index) 0 # ../aindex 1 (Select menu for area index 1) >> OSPF Area (index) 1 # areaid 0.0.0.1(Set the area ID for OSPF area 1) >> OSPF Area (index) 1 # type transit (Define area as transit type) >> OSPF Area (index) 1 # enable (Enable the area) 6. Define the stub area. >> OSPF Area (index) 1 # ../aindex 2 (Select the menu for area index 2) >> OSPF Area (index) 2 # areaid 0.0.0.2(Set the area ID for OSPF area 2) >> OSPF Area (index) 2 # type stub (Define area as stub type) >> OSPF Area (index) 2 # enable (Enable the area) 7. Attach the network interface to the backbone. >> OSPF Area (index) 2 # ../if 1 (Select OSPF menu for IP interface 1) >> OSPF Interface 1 # aindex 1 (Attach network to transit area index) >> OSPF Interface 1 # enable (Enable the transit area interface) 8. Attach the network interface to the transit area. >> OSPF Interface 1 # ../if 2 >> OSPF Interface 2 # aindex 2 >> OSPF Interface 2 # enable (Select OSPF menu for IP interface 2) (Attach network to stub area index) (Enable the stub area interface) OSPF 126
