ماهو rip protocol?

The Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocol, which employs the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops allowed for RIP is15. This hop limit, however, also limits the size of networks that RIP can support. A hop count of16 is considered an infinite distance, in other words the route is considered unreachable.

برتوكول رواتنق وهو تابع لفئة distance vector في التحديث يرسل أبديت تحتوي على network+metric ويتم حساب metric بطريقة : hop count عدد الرواتر التي سوف تقفزها لتصل إلى الشبكة المطلوبة وأقصى عدد يمكن أن تقفزه15 رواتر فقط ويرسل الابديت كل30 ثانيه او لو حدث تغير في الشبكة وينقسم الى قسمين :V1 و V2 ويعتبر النسخه الثانيه افضل وهذا البروتوكول ستاندر يعمل على جميع أجهزه الرواتر سيسكو وغيرها من الشركات 

it's Routing information protocol (RIP)

it's on of the oldest distance vector rounting protocol

metric : Number of hops

count of infinity problem :16 hop

rounting loops can occur

it's open standard

routing updates are broadcast  RIP VI every30 sec

but in RIP V2 multicast every30 sec

RIP V1 is classful but RIP v2 is classless

hold timers :180 sec

invalid timer :180 sec

flush timer :240 sec

RIP is the oldest routing protocol, basically for a very small network with limitation of15 routers only. not much used these days. not considered as the best option to go for. while is still used in some wireless devices. independent of devices can be configured on all network equipments. supports MD5 encryption. easy to configure. supports classful(RIP) and classless routing(RIPv2). IPV6 support on RIPng. use split-horizon and poison reverse to avoid loops. metric is hop count (16 hop is marked unreachable).
