8.3.2.39 ip ospf dead-interval
ip ospf dead-interval com mand sets the OSPF dead interval for the specified interface. The value for
<seconds> is a valid positive integer, which rep resents the length of time in second s that a router's Hell o
packets have not been seen before its neighbor route rs declare tha t the router is down. The va lue for the
length of time must be the same for all ro uters attached to a common network. This value should be som e
multiple of the Hello Interval (i.e. 4). Valid values range in seconds from 1 to 2147483647. no ip ospf
dead-interval comman d sets the default OSPF dead interval for the specified interface.

length of time must be the same for all routers attached to a network. Valid values range from 1 to 65535.

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 broadca st. 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 net work, OSPF can operate more efficiently by treating th e network as a
