Multi-Process and Multi-Instance
The multi-process feature associates a RIP process with multiple interfaces, ensuring that the specific process performs all the protocol-related operations only on these interfaces. With the multi-process feature, multiple RIP processes can run on a device independently. Route exchange between RIP processes is similar to route exchange between routing protocols.
RIP multi-instance associates a VPN instance with a RIP process so that the VPN instance can be associated with all interfaces on this process.
