Imagine an OpenStack cloud that consists of a single vlan provider network with the segmentation ID 100. Three instances have been connected to the network. As a result, the network architecture within the compute node resembles the following:

Figure 4.1

In Figure 4.1, three virtual machine instances are connected to a Linux bridge named brqXXXX via their respective tap interfaces. When the first instance was launched and connected to the network, Neutron created the bridge and a virtual interface named eth1.100 and automatically connected the interface to the bridge. The eth1.100 interface is bound to physical interface eth1. As traffic ...
