TIP: an area ID of 0.0.0.0 indicates the OSPF backbone.

Neighbor Speciﬁes the ID of adjacent, reachable routers.

TransitDelay Speciﬁes the estimated number of seconds required to transmit a

link state update packet over the virtual interface. Transit delay is

expressed as an integer between 0-3600. The default value is 0.

RetransInterval Speciﬁes the number of seconds between link state advertisement

retransmissions for adjacencies belonging to the virtual interface. The

retransmit interval is also used to transmit database description and

link state request packets. The retransmit interval is expressed as an

interval between 0-3600. The default value is 5.

HelloInterval Speciﬁes the interval, in seconds, between the Hello packets sent by

the router on the virtual interface. TIP: This value must be the same

for all routers attached to a common network. The hello interval is

expressed as an integer between 1-65535. The default value is 10.

RtrDeadInterval Speciﬁes the number of seconds since a router last transmitted hello
