VLAN communication between core switches
A VLAN is a broadcast domain that lives inside your switch. Instead of buying five physical switches for five departments, you buy one switch and create five VLANs. When a frame needs to cross between switches, it gets a 4-byte tag. A VLAN is a switched network that is logically segmented on an organizational basis, by functions, project teams, or applications rather than on a physical or geographical basis. " The. The Physical topology depicts a switch and four hosts in two different VLANs – Host A and Host B are in VLAN 20 and Host C and Host D are in VLAN 30. Despite all four. Inter-VLAN routing is a network configuration technique that allows communication between devices on different VLANs (Virtual Local Area Networks) within the same network What's in this article? VLANs are commonly used to segment a network, improving performance and security by isolating traffic. Nexus is the new Cisco brand of next generation switches (which include models such as 3000, 7000, 9000 series etc) for satisfying the needs of modern networks and data centers. Cisco NX-OS (Nexus Operating System) is the software which is powering this new generation of switches and has many. In this lesson, we will learn to configure a multilayer switch (also called Layer 3 switch) to perform inter-VLAN routing, which was previously done using an actual router. -
