Choose from the following options to establish a virtual link that connects an OSPF
area to the backbone area (area 0.0.0.0) without being physically connected to the
OSPF backbone area:
• If you want to configure an OSPF virtual link that contains the default parameters
for the hello-interval, retransmit-interval, transmit-delay, dead-interval,
authentication-key, and message-digest-key parameters, use the area
virtual-link command in Router Configuration mode, as shown below:
MOT(config-ospf)#area {<area-id> | <ip-address>} virtual-link <router-id>
where:
area-id is the OSPF area IP address or number.
ip-address is IP address associated with the OSPF area ID.
<router-id> is the router ID 32-bit IP address associated with the virtual link
neighbor.
• If you want to configure the time in seconds between hello packets on and
interface for the OSPF virtual link, use the area virtual-link hello-interval
command in Router Configuration mode, as shown below:
MOT(config-ospf)#area {<area-id> | <ip-address>} virtual-link <router-id>
hello-interval <seconds>
where:
area-id is the OSPF area IP address or number.
ip-address is IP address associated with the OSPF area ID.
<router-id> is the router ID 32-bit IP address associated with the virtual link
neighbor.
<seconds> is the hello interval value in seconds that must be the same for all
routers and access servers attached to a common network.
