ip default-network:

-> To select a network as a candidate route for
computing the gateway of last resort , use the
"ip default-network" command in global config mode

USAGE GUIDELINES:

-> The cisco ios software uses both ad and metirc info to
determine the default route. multiple ip default-network
commands can be given.

-> All candidate default routes , both static (flagged by
ip default network command ) and dynamic , appear in the
routing table preceeded by asterisk

-> If the ip routing table indicates that the specified network
number is subnetted and a non zero subnet number is specified
,then the system will automatically config a static summ route

-> The static summary route is configured instead of a default
network . The effect of the static summary route is to
cause traffic destined for subnets that are not explicitly
listed in IP routing table to be routed using the
specified subnet
