Viewing OSPF Virtual Link Summary Table
Non-Configurable Data
Area ID - The Area ID portion of the virtual link identification for which data is to be displayed. The Area
ID and Neighbor Router ID together define a virtual link.
Neighbor Router ID - The neighbor portion of the virtual link identification. Virtual links may be
configured between any pair of area border routers having interfaces to a common (non-backbone)
area.
Hello Interval - The OSPF hello interval for the virtual link in units of seconds. The value for hello
interval must be the same for all routers attached to a network.
Dead Interval - The OSPF dead interval for the virtual link in units of 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 common network, and should be a multiple of
the Hello Interval (i.e. 4).
Retransmit Interval - The OSPF retransmit interval for the virtual link in units of seconds. This
specifies the time 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.
Iftransit Delay Interval - The OSPF Transit Delay for the virtual link in units of seconds. It specifies the
estimated number of seconds it takes to transmit a link state update packet over this interface.
