The no form of this command removes the virtual link :
no area area-id virtual-link router-id [ authentication [ message-digest | null ]]
[ hello - interval seconds ] [ retransmit-interval seconds ] [ transmit-delay seconds ]
[ dead-interval seconds ] [ authentication-key key | message-digest -key keyid md5
key ]
Mode
Router configuration: XSR(config-router)#
Defaults
• hello ‐ interval seconds: 10 seconds
• retransmit ‐ interval seconds: 5 seconds
• transmit ‐ delay seconds: 1 second
• dead ‐ interval seconds: 40 seconds
• authentication ‐ key key: No default
• message ‐ digest ‐ key keyid md5 key: No default
Example
The following example, as illustrated in Figure 5 ‐ 1 , shows the virtual link configuration for two
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
