neutron existing subnet
my vlans for the virts have gateways on the cisco router upstream so I do not need to assign a gateway , but I cannot figure out how to create a subnet to attach to a network without assigning a gateway , and when I do assign the cisco gateway as the subnet gateway , my virts work perfectly but then my router starts complaining about duplicate ip addresses , the subnet gateway I assign gets assigned to an interface on the router . any suggestions ?
