area area-id virtual-link ip-address
The options for using this syntax are:
• area area-id virtual-link ip-address authentication-key key
• area area-id virtual-link ip-address dead-interval seconds
• area area-id virtual-link ip-address hello-interval seconds
• area area-id virtual-link ip-address retransmit-interval seconds
• area area-id virtual-link ip-address transmit-delay seconds
Syntax Description
area-id Specifies the transit area for the virtual link. Valid values are
decimal values or IP addresses. A transit area is an area
through which a virtual link is established.
ip-address Specifies the IP address of the ABR. A virtual link is
established from the ABR, where virtual link configuration
is taking place.
authentication-

routers on a network must have the same password.
dead-interval
seconds
Specifies the number of seconds that the hello packets of a
router are not communicated to neighbor routers before the
neighbor routers determine that the router sending the hello
packet is out of service. This value must be the same for all
nodes attached to a certain subnet, and it is a value ranging
from 1 to 8192.
hello-interval
seconds
Specifies the number of seconds between hello packets on
an interface. This value must be the same for all nodes
attached to a network and it is a value ranging from 1 to
