[Openstack] [Neutron] Need L2 Connectivity between the extra two nics between the VMs created on OpensStack

What type of L2 communication do they need to do? If it's ethernet, then
just attaching two ports to a network using one of the reference ML2
drivers (i.e. OVS or LinuxBridge) will give you L2 ethernet connectivity
via virtual switches.

If you want two VMs connected via a direct connect that passes arbitrary
frames directly without switching so you can use non-ethernet protocols,
then I don't believe any of the plugins support a model like that.
