Point-to-Point Interfaces On point-to-point networks, an OSPF
router dynamically detects its neighbor router by sending OSPF Hello
packets. The following statements are defined for a point-to-point
interface:
• retransmitinterval is the time interval (in seconds) between the
retransmission of link states, database descriptions, and link state
request packets. This value must exceed the expected round-trip
delay between any two routers in the network. A sample value for a
LAN is 5 seconds.
Default: None (you must specify a value)
Range: 0 – 65535
• hellointerval specifies the time interval (in seconds) between
transmission of OSPF Hello packets. Smaller intervals ensure that
changes in network topology are detected faster. A sample value for
an X.25 network is 30 seconds. A sample value for a LAN is 10
seconds.
Default: None (you must specify a value)
Range: 0 – 255
NOTE The hellointerval value must be the same for all OSPF routers.
