RIP ROUTING INFORMATION PROTOCOL

RIP:rip is a standardized distance vector routing protocol ,designed for use on smaller networks.Rip was one of the first true distance vector routing protocols,and supported on a wide variety of system .

FUNCTION OF RIP

1. Rip sends out periodic routing updates every 30 sec
2. Rip uses metric for the selection of best path which is hope count 
3. Rip sends out the full routing table every periodic updates 
4. Rip uses the Bellman-Ford distance vector algorithm to determine the best path to a particular destination 
5. Rip is class full routing protocol 
6. RIP full update is limited by split horizon rule 
7. Rip support IP and IPX routing 
8. Rip utilizes UDP port 520
9. Rip administrative distance is 120
10. Rip have mix mum hope count is 15
11. Rip invalid timer is 180 
12. Rip hold timer is 180 
13. Rip flash timer is 240 
14. Rip version one broadcast address is 255.255.255.255
15. Rip does not support VLSM 
16. Rip does not support authentication 

WHAT IS METRIC 

The parameter with help of which we can select best path are called metric 

WHAT IS HOPE COUNT 

The number of routers (hopes) between a router and destination subnet  are called hope count 

WHAT IS CLASS FULL ROUTING 

These are those protocol which have no subnet mask and only show network are called class full routing example is RIP 

RIP VERSIONS 

Rip has two version 

1. RIP VERSION 1
2. RIP VERSION 2
