Configuring the OSPF Protocol
Chapter 3 73
• routerdeadinterval specifies the time interval (in seconds) for
which the Hello packets are not received from a router before it is
considered down or inactive by its neighbors. This value must be a
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.
You can define a point-to-point interface with or without a
nonbroadcast clause. If you specify the nonbroadcast clause, then
you must define the pollinterval statement.
• pollinterval specifies a rate at which hellos are sent when a
neighboring router becomes inactive (a router is considered inactive
when hellos have not been received from the router for the amount of
time specified by the routerdeadinterval definition). The value of
pollinterval must be larger than the value of hellointerval. A
sample value for an X.25 network is 2 minutes.
Default: None (you must specify a value)
Range: 0 – 255
If the device at the other end of the point-to-point network is not an
OSPF router, you can prevent sending Hello packets to that OSPF
router using the stubhosts statement. stubhosts specifies the IP
address or domain name of the non-OSPF host. The cost of sending a
packet to the host must also be specified (in most cases, the host has
only a single connection to the network, so the cost configured has no
effect on routing).
