Items Description
“Virtual Link...” This line specifies the OSPF neighbor to which the virtual link was created
and the link’s status.
“Run as...” This line states the nature of the virtual link.
“Transit area...” This line identifies the area through which the virtual link was created, the
interface used, and the cost assigned to that link.
“Transmit Delay...” This line displays the transmit delay assigned to the link and the State of
the OSPF neighbor.
“Timer intervals...” This line displays the timer values assigned to the virtual link. The timers
are Hello is hello-interval, Dead is dead-interval, Wait is transmit-delay,
and Retransmit is retransmit-interval.
“Hello due...” This line displays the amount of time until the next Hello packet is
expected from the neighbor router.
“Adjacency State...” This line displays the adjacency state between neighbors.
