RIPng supports multi-process and multi-instance, which simplifies network management and improves service control efficiency. Multi-process allows a set of interfaces to be associated with a specific RIPng process, which ensures that the specific RIPng process performs all the protocol operations only on this set of interfaces. Therefore, multiple RIPng processes can run on one router, and each process manages a unique set of interfaces. In addition, the routing data of each RIPng process is independent; however, processes can import routes from each other.
On routers that support VPN, each RIPng process is associated with a specific VPN instance. Therefore, all the interfaces associated with the RIPng process need to be associated with the RIPng process-related VPN instance.
