Configuring RIP in SonicOS Enhanced Routing Information Protocol (RIP) is a distance-vector routing protocol that is commonly used in small homogeneous networks. Using RIP, a router periodically sends its entire routing table to its closest neighbor, which passes the information to its next neighbor, and so on. Eventually, all routers within the network has the information about the routing paths. When attempting to route packets, a router checks the routing table and selects the path that requires the fewest hops. SonicWALL appliances support RIPv1 or RIPv2 to advertise its static and dynamic routes to other routers on the network. Changes in the status of VPN tunnels between the SonicWALL and remote VPN gateways are also reflected in the RIPv2 advertisements. Choose between RIPv1 or RIPv2 based on your router’s capabilities or configuration. RIPv1 is an earlier version of the protocol that has fewer features, and it also sends packets through broadcast instead of multicast. RIPv2 packets are backwards-compatible and can be accepted by some RIPv1 implementations that provide an option of listening for multicast packets. The RIPv2 Enabled (broadcast) selection broadcasts packets instead of multicasting packets, and is for heterogeneous networks with a mixture of RIPv1 and RIPv2 routers. The images in this section are displaying management interfaces running SonicOS 5.9 and higher firmware versions.
