You can deploy Branch Gateway in a LAN using the port and switch redundancy configuration. You can connect each LAN port on the front panel of Branch Gateway to two LAN switches.
Configure one of the ports on the Ethernet LAN as the active primary link and the other as the standby, disabled link. When the gateway determines a primary link failure or malfunction of the switch attached to it, the gateway automatically fails over to the secondary link to the backup switch. Both LAN ports of the peer LAN switch ports must be enabled for the gateway to fail over to the secondary link.
