Hi,
     From the qrouter able to ping external and dhcp ip but vm is not
getting
dhcp ip address when I use interface_driver
=neutron.agent.linux.interface.OVSInterfaceDriver
the dhcp-agent.ini.

if I use neutron.agent.linux.interface.BridgeInterfaceDriver as my
interface driver vm is getting the ip address

but unable to reach the vm from the qrouter.



in l3-agent.ini if i use interface_driver =
neutron.agent.linux.interface.OVSInterfaceDriver
(qr interface is getting vlan tag as 1) and
I am able to reach the external network from qrouter but unable to ping the
vm.

but if I use interface_driver =
neutron.agent.linux.interface.BridgeInterfaceDriver(qr
interface is set with dead vlan tag 4095)

if this is the case I am able to reach the vm from qrouter but from qrouter
unable to reach the external network.


Thanks & Regards
Amit K
