RIPng

The RIPng IGP uses the Bellman-Ford distance-vector algorithm to determine the best route to a destination, using hop count as the metric. RIPng allows hosts and routers to exchange information for computing routes through an IP-based network. RIPng is intended to act as an IGP for moderately-sized autonomous systems. 

RIPng is a distinct routing protocol from RIPv2. The implementation of RIPng in Juniper devices is similar to that of RIPv2 but has the following differences: 

• RIPng does not need to implement authentication on packets. 
• The device does not support multiple instances of RIPng. 
• The device does not support RIPng routing table groups.
