Amogh,

does your provider network in your testing environment support VLAN segregation?

[Amogh (amogh-r-mavinagidad)]

@Hong Guang: seems I have to configure my environment and retest this bug.

Check the config file /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
tenant_network_types = vxlan
type_drivers = local,flat,vlan,gre,vxlan
mechanism_drivers = openvswitch,linuxbridge

So we should choose vxlan in 'Provider Network Type'

This completely depends on deployments.

Operators should configure 'supported-provider-types' settings depending on their deployments. [1]
