RackSwitch G8000: Application Guide
5. Define the transit area.
The area that contains the virtual link must be configured as a transit area.
RS G8000(config-router-ospf)# area 1 area-id 0.0.0.1
RS G8000(config-router-ospf)# area 1 type transit
RS G8000(config-router-ospf)# area 1 enable
RS G8000(config-router-ospf)# exit
6. Attach the network interface to the backbone.
RS G8000(config)# interface ip 1
RS G8000(config-ip-if)# ip ospf area 0
RS G8000(config-ip-if)# ip ospf enable
RS G8000(config-ip-if)# exit
7. Attach the network interface to the transit area.
RS G8000(config)# interface ip 2
RS G8000(config-ip-if)# ip ospf area 1
RS G8000(config-ip-if)# ip ospf enable
RS G8000(config-ip-if)# exit
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 #2 in
RS G8000(config)# router ospf
RS G8000(config-router-ospf)# area-virtual-link 1 area 1
RS G8000(config-router-ospf)# area-virtual-link 1 neighbor-router
10.10.14.1
RS G8000(config-router-ospf)# area-virtual-link 1 enable
Configuring OSPF for a Virtual Link on Switch #2
1. Configure IP interfaces on each network that will be attached to OSPF areas.
In this example, two IP interfaces are needed:
– Interface 1 for the transit area network on 10.10.12.0/24
– Interface 2 for the stub area network on 10.10.24.0/24
RS G8000(config)# interface ip 1
RS G8000(config-ip-if)# ip address 10.10.12.2
RS G8000(config-ip-if)# ip netmask 255.255.255.0
RS G8000(config-ip-if)# enable
RS G8000(config-ip-if)# exit
RS G8000(config)# interface ip 2
RS G8000(config-ip-if)# ip address 10.10.24.1
RS G8000(config-ip-if)# ip netmask 255.255.255.0
RS G8000(config-ip-if)# enable
RS G8000(config-ip-if)# exit
