Blocking Unknown Unicast Flooding
Perform this task to disable flooding of unknown unicast traffic at the bridge domain level.
You can disable flooding of unknown unicast traffic at the bridge domain, bridge port or access pseudowire
levels. By default, unknown unicast traffic is flooded to all ports in the bridge domain.
If you disable flooding of unknown unicast traffic on the bridge domain, all ports within the bridge domain
inherit this configuration. You can configure the bridge ports to override the bridge domain configuration.
