There is no redundancy provided on LAN1. Communica-tions to SCADA is provided through LAN2. P2 and P3 are connected to LAN2, where P2 is the primary channel and P3 isthe redundant channel. In this configuration, P3 uses the IP and MAC address of P2.Figure 5–4: MULTIPLE LANS, WITH REDUNDANCYMultiple LANS, No RedundancyThe following topology provides local configuration/monitoring through EnerVista software on LAN1, to which port 1 (P1) isconnected, access to the public network on LAN2, to which port 2 (P2) is connected and communications with SCADA onLAN3, to which port 3 (P3) is connected.
