servers attached to a common network. The default is 10
seconds.
retransmit-interval seconds (Optional) Time (in seconds) between link-state
advertisement (LSA) retransmissions for adjacencies
belonging to the interface. The retransmit interval is the
expected round-trip delay between any two routers on the
attached network. The value must be greater than the
expected round-trip delay. The default is 5 seconds.
transmit-delay seconds (Optional) Estimated time (in seconds) required to send a
link-state update packet on the interface. The integer value
that must be greater than zero. LSAs in the update packet
have their age incremented by this amount before
transmission. The default value is 1 second.
dead-interval seconds (Optional) Time (in seconds) that hello packets are not seen
before a neighbor declares the router down. The dead
interval is an unsigned integer value. The default is four
times the hello interval, or 40 seconds. As with the hello
interval, this value must be the same for all routers and
access servers attached to a common network.
Default
area-id: No area ID is predefined.
router-id: No router ID is predefined.
hello-interval seconds: 10 seconds
retransmit-interval seconds: 5 seconds
transmit-delay seconds: 1 second
dead-interval seconds: 40 seconds

Usage
In OSPF, all areas must be connected to a backbone area. If the connection to the backbone is lost, it
can be repaired by establishing a virtual link.
The smaller the hello interval, the faster topological changes will be detected, but more routing traffic
will ensue.
The setting of the retransmit interval should be conservative, or needless retransmissions will result.
The value should be larger for serial lines and virtual links.
The transmit delay value should take into account the transmission and propagation delays for the
interface.
Examples
The following example establishes a virtual link with default values for all optional parameters:
