Name Definition
area-id IP address that represents the area-id for the system.
router-id Router ID associated with the virtual link neighbor. The router ID
appears in the show ip ospf display. It is internally derived by each
router from the router's interface IP addresses. This value must be
entered in the format of an IP address. There is no default.
hello-interval <seconds> Time in seconds between the hello packets that the Cisco IOS
software sends on an interface. Unsigned integer value to be
advertised in the software's hello packets. The value must be the
same for all routers and access servers attached to a common
network. The default is 10 seconds.
retransmit-interval
<seconds> Time in seconds between link state advertisement retransmissions
for adjacencies belonging to the interface. 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.
dead-interval <seconds> Time in seconds that a software's hello packets are not seen before
its neighbors declare the router down. 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.
