You need to enable VLAN tagging (in your case it is 102) on the switch side to allow traffic. In your case, such packets are getting dropped by the switch.

My existing working environment: 1) 3 Hosts (controller1 and compute1 & compute2 nodes) with single network interface in individual host. 2) Was using FlatDHCPManager so far, now I've changed it to Vlan mode by following below doc: http://docs.openstack.org/grizzly/openstack-compute/admin/content/configuring-vlan-networking.html 3) I've only one project "demo" and vlan102 is tagged to that. Problem: 1) Instances of the same compute1 node can talk each other but not with the instances of neighbour compute2 node. 2) Compute1 node cannot ping/ssh to instances of their neighbor compute2 node. Whereas any instance of any compute node can reach (ping/ssh) to Compute/Controller host network and their gateway. My understanding is, vlan separates the network between different projects. In my case, it looks like compute nodes has been separated with their individual instances. Could anyone please guide, what and where I'm missing? PS - In FlatDHCP mode, every instances can talk to each other irrespective of the hosting node and accessible from any host of the same network. Thanks, Amogh
