VM1 ---> Layer2 Device ---> VM2 + VM3 + .....+ VMn

I'm looking for help on this above given scenario.

The Layer2 device is supposed to be present in an inline mode so that it can filter the traffic ( based on criteria ) where the traffic will be landing on VM1 and then it will be forwarded to other VMs but the traffic will be caputred at Layer 2 by the external Layer2 device sitting outside the OpenStack setup ( can be connected to the OpenStack setup using additional NICs )

plus some other questions.

Note: this is a complete KILO OpenStack setup running on 3 nodes ( VM nodes from ESXi Server ) and works perfectly nice with default configuration using gre as tenant network types with OVS ( from for KILO )

I got it like below.

1) enabled multiple external networks with single L3 agent. 2) configured one VM to use 1st external network ( connected through my L2 device to network switch) 3) integrated rest of the VMs be connected using 2nd external network.

connectivity is possible only on floating IP addresses between VM in order to use my L2 device.

Its working like a charm.
