11.4.3.11 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.
