y might pick up R2's route as an alternative to its failed direct connection, causing a routing loop. Split horizons are implemented because they provide extra stability.Split horizons with poison reverse is the same as above, with the exception of instead of excluding the route back, it sets their metric to infinity.IMPROVEMENTS:The latest enhancement to RIP is the RIP2 specification, which allows more information to be included in RIP packets and provides a simple authentication mechanism. It expands the amount of useful information carried in RIP datagrams and adds security provisions.SUMMARY:RIP is an efficient routing protocol used in moderate sized networks. Its basic algorithm structure is a distance vector algorithm using hop count and other metrics to traverse the network. The message format was described as well as the RIPs limitations. I then introduced RIP2 that solves many of RIPS limitations. RIP has been around since the days of ARPANET and should be here for quite some time....
