There's your problem. Use a bonding method that can detect uplink failure.

I like the active-standby w/ ARP probes of the gateway, on Linux (which 
given you say "bond0" is, I assume, what you mean)

As others have pointed out, if you can't do this then some triggered 
event, possibly via EEM, might work. But frankly I dislike those 
solutions - "smarts in the network" versus "smarts at the edge" and all...
