8.3.2.40 ip ospf hello-interval
ip ospf hello-interval command sets the OSPF hello interval for the specified interface. The value for
seconds is a valid positive integer, which represents the length of time in seconds. The value for the
length of time must be the same for all routers attached to a network. Valid values range from 1 to
65535. no ip ospf hello-interval command sets the default OSPF hello interval for the specified
interface.

8.3.2.41 ip ospf network
ip ospf network command to configure OSPF to treat an interface as a point-to-point rather than
broadcast interface. The broadcast option sets the OSPF network type to broadcast. The point-to-point
option sets the OSPF network type to point-to-point. OSPF treats interfaces as broadcast interfaces by
default. (Loopback interfaces have a special loopback network type, which cannot be changed.) When
there are only two routers on the network, OSPF can operate more efficiently by treating the network as
a point-to-point network. For point-to-point networks, OSPF does not elect a designated router or
generate a network link state advertisement (LSA). Both endpoints of the link must be configured to
operate in point-to-point mode..
no ip ospf network command to return the OSPF network type to the default.
Syntax
ip ospf network {broadcast|point-to-point}
