If Ip routing is not enabled, then Ip Packets with a destination outside the
local subnet are discarded in the router.
Default route (ip route 0.0.0.0 0.0.0.0 1.2.3.4)
Default Gateway (ip default-Gateway 1.2.3.4)
Both create a static Gateway of last resort that is redistributed by IGP's
except for IGRP and EIGRP.
EIGRP and IGRP do not understand default routes created this way, so they
require a different command.
ip Default-Network 10.0.0.0
This command redistributes a route to all of the IGRP/Eigrp routers that
says "If you don't know where it goes, then send it to Network 10.0.0.0, one
of the routers there will get it to the right place."
Hope that helps.
In case your brain wasn't full enough, here's a tidbit on Default route
administrative distances.
ip route 0.0.0.0 0.0.0.0 1.2.3.4 - Default Admin Distance 1
ip route 0.0.0.0 0.0.0.0 Serial 0 - Default Admin Distance 0
Static routes default to an Admin Distance of 1, Directly connected networks
default to a Admin Distance of 0. Therefore, a default route to an
interface is seen as a directly connected network.

hi guys,
Please verify if I am right
default route and default-network serves the same
purpose , they both defines the gateway of last resort
whereas, default-gateway defines the gateway of last
resort if ip routing is not enable
Correct me if I am wrong
thanks
