Abstract
A first addressing message is received at a first switch in a network fabric indicating that a first virtual machine has undergone migration from connection to a first virtual switch at a first server to connection to a second virtual switch at a second server. A route advertisement message is then transmitted from the first switch to at least a second switch in the network fabric. This route advertisement is configured to cause the second switch to transmit a second addressing message to a second virtual machine connected to the first virtual switch. The second addressing message provides the second virtual machine with updated addressing information for the first virtual machine. A third addressing message is also transmitted from the first switch to the first virtual machine to provide the first virtual machine with updated addressing information for the second virtual machine.
