I know when strictly using Openvswitch, promiscuous mode was required on the network adapter being used for br-ex. With Ml2, the documentation does not say. Should the adapter be set with promiscous when using ml2?

Is it a problem to try both options and see what happens ?
Per http://docs.openstack.org/trunk/insta... (IceHouse) 

Configure the EXTERNAL_INTERFACE without an IP address and in promiscuous mode. Additionally, you must set the newly created br-ex interface to have the IP address that formerly belonged to EXTERNAL_INTERFACE.

This is listed under the openvswitch plugin however I am using the ml2 plugin. This is where I am confused,

Can you work with ML2 plugin without OVS agent up :-

[root@icehouse1 neutron(keystone_admin)]# cat plugin.ini
[ml2]
type_drivers = vlan
tenant_network_types = vlan
mechanism_drivers = openvswitch
[ml2_type_vlan]
network_vlan_ranges = physnet1:100:200
[ovs]
network_vlan_ranges = physnet1:100:200
tenant_network_type = vlan
enable_tunneling = False
integration_bridge = br-int
bridge_mappings = physnet1:br-p4p1
local_ip = 192.168.0.127
