What is Routing Information Protocol (RIP)?

• The Routing Information Protocol (RIP) is a dynamic routing protocol that finds the optimum path between the source and destination networks by using hop count as a routing metric. It is a distance-vector routing protocol with an AD value of 120 that operates at the OSI Network layer. The RIP protocol uses port 520.
• Network updates are exchanged on a regular basis.
• Routing information (updates) are always broadcast.
• Routing tables in their entirety are sent in updates.
•  Routing information received from nearby routers is always trusted by routers. This is also known as rumour routing.
