Using link aggregation on the compute node

Link aggregation or bonding is a way to combine multiple physical network links to a logical link.

Link aggregation is used as a means to provide higher bandwidth and redundancy against link failure. In this recipe, we will see how to configure link aggregation in order to connect the virtual switch on an OpenStack node to the physical switch.

We will assume that the virtual switch used on the OpenStack node is Open vSwitch and configure link aggregation with Link Aggregation Control Protocol (LACP):

Getting ready

For this recipe, we will need the following information:

• SSH-based login for the Compute and Network node
• Details of the Network interface to use for link aggregation

How to do it…

The following steps will show you how to configure link aggregation on a Compute or a Network node and update Neutron to use the bonded interface for the tenant data traffic:

1. With the appropriate credentials, SSH into the Compute node.
2. Add a bridge on the Open...
