You specify the netmask for the network interfaces you are using, which 
would be eth0 and bond0. The two may be different.

The default gateway is the IP address of the router that forwards 
packets to places you don't have explicit routes for. It's a single 
address, not a network, and so it does not have a netmask. When you 
specify a gateway, a default route will be set up with destination 
0.0.0.0, netmask 0.0.0.0 and your specified gateway address. You don't 
need to specify anything else.
