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):
For this recipe, we will need the following information:
