==Summary==
<b>Virtual Router Redundancy Protocol</b> (<b>VRRP</b>) is a computer networking protocol used for automatic default gateway selection for clients on a LAN network in case the main router (Master) becomes unavailable. Another VRRP router (Backup) then assumes the role of Master; thus backing up the connection.

The <b>VRRP Configuration</b> section lists VRRP instances currently existing on the device. By default the list is empty thus, you must first create at least one instance in order to begin configuring VRRP.
