Abstract
In response to receiving an ASR message, a VTEP generates a specially modified control plane message advertising the IP-to-MAC binding of the ASR message. The control plane message may be modified to indicate that it is not to be used for MAC learning. The control plane message is advertised over the network. When an intended recipient receives the message, it uses that message just for the IP-to-MAC binding. When an unintended recipient receives the message, it may drop it as invalid.
