Which two message types does RIP use?

RIP (Routing Information Protocol) utilizes the Request and Response messaging types to facilitate communication between routers. When a router needs to learn about the routes of its neighbor, it sends a Request message. This is essentially a solicitation for routing information. The neighboring router then responds with a Response message, which contains the routing updates, providing the requested information on available routes and their metrics.

The Request message serves to inquire about routes when a router starts up or when it needs to refresh its route table, while the Response message contains the routing information that is sent periodically or in reply to a request. This two-way interaction allows RIP routers to maintain updated routing tables effectively and ensures that all devices on the network have consistent and current routing information.
