MAC Address Withdrawal is a mechanism described in [RFC4762] to
remove or unlearn MAC addresses that have been dynamically learned,
for faster convergence. Failure of mechanisms that control loop free
connectivity (e.g Split Horizon) among VPLS PE nodes may cause MAC
Address Withdrawal messages looping among those nodes, leading to
Denial of Service (DoS) or complete failure of control plane in the
PE nodes. This document describes a mechanism to detect and prevent
loops of MAC Address Withdrawal messages in a VPLS PE node on such
failures.
