Hello,

I have some questions about the quantum demo install found here : 
http://docs.openstack.org/trunk/openstack-network/admin/content/demo_logical_network_config.html

Can someone please tell me what should the IP address of eth2 ( bridged 
on br-ex) ?
and how it's related to the external network related later ?

quantum subnet-create ext_net 172.24.4.224/28 -- --enable_dhcp=False

+------------------+--------------------------------------------------+

I would like also to query about how to get the gateway_ip ? should it 
be created by default or mapped to the IP address of eth2 ??

Please shed some light on this matter
