Routing Information Protocol enables the network information exchange between the routering devices. RIP version 2 has ability to exchange the VLSM prefixes contrary to RIP version 1 which exchange only summary routes. RIP is vendor independent protocol so that can be enabled on vendor-mixed infrastructures. RIP has scaling limitation of 15 hops at most.. To enable RIP define the process, version and range of interfaces (in the form of IP addressing) on whish RIP will be enabled:

Router(config) router rip
Router(config-router) version 2
Router(config-router) network 10.0.0.0
Router(config-router) no auto-summary
