Abstract:
MAC Address Withdrawal is a mechanism described in [RFC4762] to
remove or unlearn MAC addresses that have been dynamically learned in
a VPLS instance, for faster convergence on topology change. Failure
of mechanisms that control loop free connectivity among VPLS PE-rs
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-rs nodes. This document describes a
mechanism to detect and prevent loops of MAC Address Withdrawal
messages in a VPLS PE-rs node on such failures.
