(Routing Information Protocol): RIP only uses hop count and is capable of performing round-robin load balancing to up to six equal-cost links.
Pinhole congestion happens when two equal-cost links are of different bandwidth, which is disregarded by RIP. RIP does not support AppleTalk.
Routing information messages including the complete routing table are sent every 30 sec by default.
(config)#router rip: enables RIP.
(config-router)#network network: limits the propagation of the RIP messages to the network. For example, if subnet 172.16.40.0 is to be used by
RIP, then network should be 172.14.0.0.
(config-router)#passive-interface type number: the interface will not send RIP messages but still receive them.
Routing loops: is due to the slow convergence of RIP and occurs when conflicting update information is received from different routers.
Maximum Hop Count: will set any network beyond a certain distance to be unreachable with the max hop count +1.
Split Horizon: enforces the rule that information cannot be sent back in the direction from which it was received.
Route Poisoning: sets down links to the unreachable value. It is followed by a poison reverse.
Hold-downs: timer that prevents conflicting rapid updates of the routing tables. Once a value is changed, the router will wait the hold-down timer
prior accepting another change.
Triggered Updates: resets the hold-down timer if the timer expires, the router receives a processing task proportional to the number of links or
