Routing Information Protocol (RIP)
Routing Information Protocol (RIP) is a true distance-vector routing protocol. RIP sends the
complete routing table to all active interfaces every 30 seconds. RIP uses the hop count only
to determine the best way to a remote network, but it has a maximum allowable hop count
of 15 by default, meaning that 16 is deemed unreachable. RIP works well in small networks,
but it’s inefficient on large networks with slow WAN links or on networks with a large number
of routers installed.
