8.3.2.39 ip ospf dead-interval
ip ospf dead-interval command sets the OSPF dead interval for the specified interface. The value for
<seconds> is a valid positive integer, which represents the length of time in seconds that a router's Hello
packets have not been seen before its neighbor routers declare that the router is down. The value for the
length of time must be the same for all routers attached to a common network. This value should be some
multiple of the Hello Interval (i.e. 4). Valid values range in seconds from 1 to 2147483647. no ip ospf
dead-interval command sets the default OSPF dead 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
