Configuring OSPF
NOTE
When you establish an area virtual link, you must configure it on both of the routers (both ends of
the virtual link).
FIGURE 99 Defining OSPF virtual links within a network
Example
Figure 99 shows an OSPF area border router, DeviceA, that is cut off from the backbone area (area
0). To provide backbone access to DeviceA, you can add a virtual link between DeviceA and
DeviceC using area 1 as a transit area. To configure the virtual link, you define the link on the
router that is at each end of the link. No configuration for the virtual link is required on the routers
in the transit area.
To define the virtual link on DeviceA, enter the following commands.
TurboIronA(config-ospf-router)#area 1 virtual-link 10.157.22.1
TurboIronA(config-ospf-router)#write memory
Enter the following commands to configure the virtual link on DeviceC.
