I wrote down a few notes on RIP routing protocol for CCNA.

RIP Routing ProtocolRIP – Routing Information Protocol
RIP is a distance vector routing protocol, it uses hop count as a routing metric.
Rip prevents routing loops by using a limit on the number of hops allowed in a path to the destination.
The maximum number of hops allowed by RIP are 15.
RIP uses Split Horizon, Route Poisoning and Hold own to prevent incorrect routing to be propagated to other routers.
Poor time convergence and scalability make RIP the lesser choice for implementation in networks.
RIP is easier to configure so it could be used for quick, small networks.
RIP uses UDP 520
RIPv1 only supports classful
RIPv2 supports VLSM
RIPng supports IPv6
