Overview of RIP
Definition
Routing Information Protocol (RIP) is a simple Interior Gateway Protocol (IGP). RIP is a Distance-Vector protocol that uses hop count to measure the distance between the local device and the destination. RIP exchanges routing information using UDP packets on UDP port 520.
Two versions are available for RIP: RIP-1 and RIP-2. RIP-2 is an extension to RIP-1.
Purpose
RIP is easy to implement, and is easier to configure and manage than OSPF and IS-IS. Therefore, RIP is applicable to small-sized networks, such as campus networks and simple LANs. It is not suitable for complex environments or large-sized networks.
