Selection Criteria
Create New Virtual Link - Select this option from the dropdown menu to define a new virtual link.
The area portion of the virtual link identification is fixed: you will be prompted to enter the Neighbor
Router ID on a new screen.
Area ID and Neighbor Router ID - Select the virtual link for which you want to display or configure
data. It consists of the Area ID and Neighbor Router ID.
Configurable Data
Hello Interval - The OSPFv3 hello interval for the specified interface in seconds. This parameter
must be the same for all routers attached to a network. Valid values range from 1 to 65,535. The
default is 10 seconds.
Dead Interval - The OSPFv3 dead interval for the specified interface in seconds. This specifies how
long a router will wait to see a neighbor router's Hello packets before declaring that the router is
down. This parameter must be the same for all routers attached to a network. This value should a
multiple of the Hello Interval (e.g. 4). Valid values range from 1 to 2147483647. The default is 40.
Iftransit Delay Interval - The OSPFv3 Transit Delay for the specified interface. This specifies the
estimated number of seconds it takes to transmit a link state update packet over the selected
interface. Valid values range from 1 to 3600 seconds (1 hour). The default value is 1 second.
Retransmit Interval - The OSPFv3 retransmit interval for the specified interface. This is the number
of seconds between link-state advertisements for adjacencies belonging to this router interface. This
value is also used when retransmitting database descriptions and link-state request packets. Valid
values range from 1 to 3600 seconds (1 hour). The default is 5 seconds.
Non-Configurable Data
State - The state of the interface.

Down - This is the initial interface state. In this state, the lower-level protocols have indicated
that the interface is unusable. In this state, interface parameters will be set to their initial
