Split Horizons are solved in RIP by limiting packets to 15 hops. In IGRP [Internet Gateway Routing Protocol], the number of hops is limited to 255. For CCNA, this solves a route loop as ports (circuits - pathways) cannot advertise (send) routes on the same port (interface) where it has received an advertisement.

Here is a brief overview of RIP [Routing Information Protocol]:

• RIP is a distance vector protocol - updates other routers periodically (continuously) - generally every 30 seconds

• Metric - routing value - is hop (router) count - how many hops to get their - default is 1 hop or “hop(e) that is gets there” RIP is limited to 15 hops
• RIP is an interior gateway protocol - in same Autonomous System - AS (carriers or service providers) (BGP-Border Gateway Protocol is the routing protocol used between AS)
• More information can be found at RFC 1058 and 1723 (RFC-Request for Comment) Information on all Internet Engineering Task Force RFCs
