Hi, Thanks for the reply.
What is the use of promiscuous mode in openstack ? Thanks Kumar From: Akilesh K [mailto:[email protected]] Sent: Thursday, June 19, 2014 5:28 PM To: Gnan Kumar, Yalla; [email protected] Subject: Re: [Openstack] GRE tunnel Openstack support multi tenant networks. That means two tenants may use the same network space. There must be some other way to isolate the networks of different tenants. So every network in Openstack is assigned a special segmentation id. In case of gre the segmentation id is the tunnel id. In case of vlan mode the segmentation id becomes the vlan id. I have some more detailed information in the below posts http://fosskb.wordpress.com/2014/06/10/managing-openstack-internaldataexternal-network-in-one-interface/ http://fosskb.wordpress.com/2014/06/19/l2-connectivity-in-openstack-using-openvswitch-mechanism-driver/ On Thu, Jun 19, 2014 at 5:12 PM, <[email protected]<mailto:[email protected]>> wrote: Hi All, What is the requirement of GRE tunneling in openstack ? Why the VMs have to communicate only through GRE tunnels ?
