Important Considerations
■
Hello packets inform other routers that the sending router is still active
on the network.
■
If a router does not send Hello packets for a period of time specified
by the dead interval, the router is considered inactive by its neighbors.
■
The virtual link Hello interval must be consistent throughout the
autonomous system.
