The S- K- and 7100-Series device supports Routing Information Protocol (RIP) Version 2. RIP is a distance‐vector routing protocol for use in small networks; it is not intended for complex networks. RIP is described in RFC 2453. A router, running RIP broadcasts, updates at set intervals. Each update contains paired values where each pair consists of an IP network address and an integer distance to that network. RIP uses a hop count metric to measure the distance to a destination and is not appropriate for situations where routes need to be chosen based on real-time parameters such as a measured delay, reliability, or load.
The S- K- and 7100-Series device implements plain text and MD5 authentication methods for RIP Version 2.
