The Routing Information Protocol Next Generation (RIPng) is a simple Interior Gateway Protocol (IGP). It is an extension to RIP on IPv6 networks. RIPng applies to small-scale networks, such as campus networks and regional networks with simple structure. RIPng is widely used on networks because it is easier to implement, configure, and manage than OSPFv3 and IPv6 IS-IS.
RIPng does not have any security authentication mechanism. For security purposes, use OSPFv3, IPv6 IS-IS, or BGP4+.
