Example
The following example, as illustrated in Figure
ABRs. ABR1 physically interfaces area 2 to the backbone (area 0.0.0.0). ABR2 physically interfaces
area 3 to area 2. A virtual link is created between the two ABRs by means of area 2, which becomes
the transit area. The RouterID for ABR1 is 192.168.33.1. The RouterID for ABR2 is 192.168.33.2.
On ABR1 enter the following commands:
XSR(config)#interface fastethernet 1
XSR(config-if<F1>)#ip address 172.16.150.1 255.255.255.0
XSR(config)#interface serial 1/0
XSR(config-if<S1/0>)#ip address 192.16.33.1 255.255.255.0
XSR(config)#router ospf 1
XSR(config-router)#network 172.16.150.0 0.0.0.255 area 0.0.0.0
XSR(config-router)#network 192.16.33.0 0.0.0.255 area 2
XSR(config-router)#area 2 virtual-link 192.16.33.2
On ABR2 enter the following commands:
XSR(config)#interface fastethernet 1
XSR(config-if<F1>)#ip address 172.15.0.1 255.255.0.0
XSR(config)#interface serial 1/1
XSR(config-if<S1/1)#ip address 192.16.33.2 255.255.255.0
XSR(config)#router ospf 1
XSR(config-router)#network 172.15.0.1 0.0.0.0 area 3
XSR(config-router)#network 192.16.33.0 0.0.0.255 area 2
XSR(config-router)#area 2 virtual-link 192.16.33.1
XSR(config-router)#
