gateway of last resort

[giacomo12]

Hi,

To set the default gateway in a Cisco router I can use:   ip default-network 0.0.0.0

I don't understand 0.0.0.0. Which is the next hop? I know the command: ip route 0.0.0.0 0.0.0.0 x.x.x.x  where x.x.x.x is the next hop

Regards

Don't use 0.0.0.0.  Use the actual next hop.

Hi,
don´t use command "ip default-network".
"ip route 0.0.0.0 0.0.0.0 interface x.x.x.x" is better for this purpose.

Command "ip default-network" is from times when classful addresses were used.
So this command has strange behaviour in classless network.

You must know what you are doing if you want to use it.

Do you have any good reason to use exactly this command ?
