Configuring the OSPF Protocol
transitdelay is the number of seconds it takes to transmit a Link
State Update Packet over this interface. This value must take into
account the transmission and propagation delays for the interface. It
must be greater than 0. A sample value for a LAN is 1 second.
Default: None (you must specify a value)
Range: Integer between 1 - 65535
priority should be configured only for interfaces to multi-access
networks. This value specifies the priority of the router to become the
Designated Router. When two routers attached to a network both
attempt to become the Designated Router, the one with the highest
router priority value takes precedence.
Default: None (you must specify a value for multi-access networks)
Range: 8-bit unsigned integer between 0 - 255. 0 means that the
router is ineligible to become a designated router on the attached
network.
hellointerval specifies the number of seconds between transmission
of OSPF Hello packets. Smaller intervals ensure that changes in
network topology are detected faster; however, routing traffic can
increase. 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: Integer between 0 - 255
NOTE The hellointerval value must be the same for all OSPF routers.
routerdeadinterval specifies the number of seconds that hello
packets are not received from a router before it is considered “down” or
“inactive” by its neighbors. This value should be some multiple of the
hellointerval value.
Default: None (you must specify a value)
Range: 0 - 65535
NOTE The routerdeadinterval value must be the same for all OSPF
routers.
