At which layer of the OSI model are routing protocols defined?

Show Suggested Answer Hide Answer
Suggested Answer: A

Routing protocols are defined at the network layer (Layer 3) of the OSI model. The network layer is responsible for routing packets across different networks using logical addresses (IP addresses). Routing protocols are used to exchange routing information between routers and to determine the best path for data delivery. Some examples of routing protocols are BGP, OSPF, RIP, and EIGRP. Palo Alto Networks devices support advanced routing features using the Advanced Routing Engine1.

Routing protocols? At the Physical layer, of course! I mean, how else are those bits gonna find their way, am I right?

Network layer, for sure. Unless this is some kind of trick question... Ooh, the suspense is killing me!

I'm feeling lucky, let's try C. Transport. Isn't that where all the port numbers and stuff are handled?

I'm not sure, but I'll go with A) Network based on what Lizbeth and Georgene said.

I agree with Lizbeth, routing protocols operate at the network layer to determine the best path for data packets.

I think it's A) Network because routing protocols deal with network layer addressing.

Hmm, I'm gonna go with D. Data Link. Gotta have those MAC addresses and all that jazz, right?

Well, duh, it's obviously the Network layer! Routing protocols are all about getting packets from point A to point B, right?
