The Routing Information Protocol (RIP) is a distance-vector dynamic routing protocol that is used by the appliance to automatically configure optimal routes based on messages received from other RIP-enabled on-link hosts (typically routers). The appliance supports both RIPv1 and RIPv2 for IPv4, and RIPng for IPv6.
Routes that are configured via these protocols are marked as type "dynamic" in the routing table. RIP and RIPng listen on UDP ports 520 and 521 respectively.
