The following methods are used to avoid Routing Loops in RIP :
* The maximum hop count mechanism can be used to block Routing Loops. Vector distance protocols use the TTL (Lifetime) value in the IP data header to avoid loops.
* Split horizontal is the setting of the route that stops the route from being advertised back to where it came from.
* Route Poisoning is another way to avoid loops. If the router finds that one of its connected routes has failed, the router will be toxic to the route by providing endless metrics to it.
