The OSI networking model defines a number of network “layers.” (Getting into each layer is beyond the scope of this article but our Network Management in a Nutshellblog post has a good recap if you want to brush up.) Layer 2 of the OSI model is known as the data link layer. The Layer 2 protocol you’re … See moreFeb 23, 2024 · The "IP" in TCP/IP is a Layer 3 protocol. In NetWare's heyday, IPX was a very popular Layer 3 protocol within the IPX/SPX protocol group. The network layer provides a logical address of an endpoint. Layer 2 addresses are typically automatically generated by the vendor during the manufacturing process. But layer 3 addresses are usually ... The lowest model of switch with Layer-3 capability is Catalyst 3560. Out-of-the-box, these series support basic Layer-3 (static routing and RIP), or you can upgrade the s/w to enhanced layer-3 (EIGRP, OSPF, BGP). My suggestion is to go straight to enhanced layer-3 model of switches, and disable ip routing.This layer combines the OSI model’s L1 and L2.
