    Information Protocol (RIP). Using RIP, routers periodically update one another and check for changes to add to the routing table. The MR814 v3 router supports both the older RIP-1 and the newer RIP-2 protocols. Among other improvements, RIP-2 supports subnet and multicast protocols. RIP is not required for most home applications.
