Configuring the OSPF Protocol

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).
