Open Stack

hey there,

I'm trying to configure two external networks for openstack. I'm using the
same l3 agent. the first external network is connected to eth1 via br-eth1
and the second is connected to eth0 via br-ex.

 You can find below my configuration. My problem is that I can't ping the
external gateways from my routers
