There are 3 ways to set a default route which is ip route, ip default-network and ip default-gateway.
ip route is mostly used as the gateway of last resort. When showing the show ip route command, the default route will be marked as S*.
ip default-network is applied for candidate default route. The ip routing must be enabled for this process to work. The command will be applied in the router to the default network. It will then notify other neigboring routers and will appear on the other routers as the default route.
To configure the default network on the main route:
(config)#ip default-network
On the other routers when show ip route, it will show the default route as
R* 0.0.0.0/0 [120/1] ...
Notice that the router will be the default route (R*) not the usual static route (S*)
ip default-gateway is used when IP routing is disabled on the router. It is basically used as a gateway from the host to the outside world.
