default route

[victormitu]

hi... there is somebody to explain me the difference between:

ip route 0.0.0.0 0.0.0.0 <next_hop>

and

ip default-network x.x.x.x

?

thanks

ip default-network x.x.x.x

This command selects a network as a candidate route for computing the gateway of last resort. If there are several choices, the one with the best metric is chosen

Using ip route 0.0.0.0 0.0.0.0 next-hop,the router will consider all of the destinations that the router does not know how to reach through some other route reachable via next-hop IP.

Moreove both the commands does the same funrction and are used for the same purpose.

Victor,

There is a great TAC document about default routes, which should answer your question and the ones that follow from it too:
