Hi,

Can anyone help elaborate why the following line of code in devstack 
which is trying to add a route for VM private network via router gateway 
IP on network node is *NOT* taken care by neutron but devstack? The 
reason to ask is that every time a router external gateway IP changed or 
a new router is added, we have to manually change this route or add a 
new one on network node.

sudo route add -net $FIXED_RANGE gw $ROUTER_GW_IP

Thanks!
