Routing Information protocol (RIP)

Routing Information protocol (RIP) is a Distance vector Protocol which used to find the best path based on the hope count in the network. RIP perform routing only single autonomous system because it is a interior gateway protocol . Number of hops in the RIP is limited that why it prevent from routing looping because no of hops will exceed (means 16 hop) considered as unreachable. RIP has max number of hop 15. In which path of remote network number of hops will be less that path considered as best path for route packet to the destination.
RIP Routing Protocol

Routing Information protocol (RIP)

There are two type version of RIP one is RIPv1 and second is RIPv2 . RIPv1 is a classfull Routing Protocol which  means all device in the network must be used same subnetmask because RIP v1 does not send update with subnetmask in the network. RIPv2 can also support authentication .


Properties of RIP
  • It can only support classfull network. 
  • It can not support classless network.
  • It can not support VLSM and CIDR.
  • It can also support subneting .
  • It has A.D is of 120.
  • It has max hop count 15.
  • It support 6 equal cost path for load balancing.


RIP uses four type of timers which help to regulate RIP performance
  • Routing update timer-: This time explain that how much time Router waits to send the updates  routing table information to all the neighbors  its time interval is 30 second.
  • Hold down timer-: This timer explain that how much time router can hold unused information this happen when received indicate that route is unreachable . the default timer is 180 second .
  • Invalid timer-: If Router has not heard update about particular route in a period when timer will over then router send out update to all the neighbor for inform that the route is invalid the default timer is 180 second.
  • Flushed timer-: It is explain that how much time a router waits to flush a route after being invalid. the default timer is 240 second.
