This is used to set a default gateway

This is used to define a static default network. It is used in tandem with
the ip route command
ex.
ip route 15.0.0.0 255.0.0.0 20.20.20.1
ip default-network 15.0.0.0
now instead of sending traffic to an interface you are sending traffic to a
network this would be used to direct traffic along a certain path
this is used when you can't get individual subnets into a routing table such
as with rip. a packet with an address for the 15.15.0.0 255.255.0.0 subnet
would use this route because 15.0.0.0 would be the longest match in the
table. once it reaches the 15.0.0.0 network it could be routed because an
interface knows its subnet

> ip route 0.0.0.0 0.0.0.0 x.x.x.x - this would be the interface to use
This sets up a default route because it would be the longest match and any
traffic not matched in the routing table would use this.
