Routing Information Protocol (RIP)

Routing Information Protocol (RIP) is used to perform routing over the network. RIP performs routing over the limited number of hop count which is 15. This means that RIP can exchange its routing table information from First router to 15th router. On 16th router the information of First router routing table can't be shared and that will become unreachable.

There are three versions of RIP

Version 1 Only supports Class Full IP address of IPv4 which means it can not support Subnetted IP Addresses.
Version 2 supports both Non-Subnetted and Subnetted IP Address of IPv4.
Version 3 supports both IPv4 and IPv6 IP Address

Advantages of RIP

RIP is standardized protocol
RIP supports VLSM (Variable Length Subnetmask)
RIP provides fastest coverage over the network
RIP fastly updates when network changes

Disadvantages of RIP

RIP works only upto 15 Hopcounts
RIP does not have concept of neighbors
RIP changes its entire table with all the devices connected to the network after every 30 seconds
