Robert,

As Simon mentioned, this isn't a feature in Grizzly yet. For now, you
can achieve similar functionality by calling the quantum-ha-tool from
stackforge[1] at a regular interval. More specifically, you're looking
for the `--replicate-dhcp` option.

     Hello,
     I guess you are running Grizzly. It requires Havana to be able to
     schedule automatically multiple DHCP agents per network.

         Hi,

         How would one make sure multiple dhcp agents run for the same
         segment?
         I currently have 2 dhcp agents running but only one is added to
         a network when the network is created.

         When I manually add the other one with "quantum
           dhcp-agent-network-add" but I would like this to happen
         automatically.

         Thx,
         Robert
