A network node is described herein which ensures that whenever an ingress station (e.g., PC) communicates a special MAC DA packet then that packet's copies are forwarded (via a high availability VLAN) to its port(s) that are associated with remote network node(s) and/or egress server(s) (e.g., firewall(s)) and not forwarded to its port(s) that are associated with data storage server(s) or ingress station(s) (e.g., PCs). The network node also ensures that whenever an ingress station (e.g., PC) communicates a normal MAC DA packet then that packet's copies are forwarded to all of its port(s) that are associated with ingress station(s), remote network node(s), egress server(s) and/or data storage server(s) so that these stations/servers can maintain their connectivity via a default VLAN.
