What is Layer 2 VLAN?
What is Layer 2 VLAN?
A VLAN is a set of logical ports that share the same flooding or broadcast characteristics and span one or more ports of multiple devices. Thus, MX Series routers or EX Series switches can function as Layer 2 switches, each with multiple bridging, or broadcast, domains that participate in the same Layer 2 network.
Is VLAN a Layer 2 or Layer 3?
VLANs are data link layer (OSI layer 2) constructs, analogous to Internet Protocol (IP) subnets, which are network layer (OSI layer 3) constructs. In an environment employing VLANs, a one-to-one relationship often exists between VLANs and IP subnets, although it is possible to have multiple subnets on one VLAN.
What is the difference between a Layer 2 VLAN and a Layer 3 VLAN?
Layer 2 is generally hardware i.e. mac address “routing” or mac tables. Layer 3 has to do with ip’s. Layer 3 devices are usually managed and they can create and route between vlans.
Is a switch Layer 2 or 3?
Layer2 is the process of using devices and MAC addresses on a LAN to segment a network. A Layer 3 switch is a switch that performs routing functions in addition to switching. Layer 2 switches perform the switching function to re-arrange the data frames from the source to its destination network.
What is layer 2 switching in networking?
A layer 2 switch is a type of network switch or device that works on the data link layer (OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded. It uses hardware based switching techniques to connect and transmit data in a local area network (LAN).
What is layer 2 configuration?
You can configure Layer 2 switching ports as access or trunk ports. Trunks carry the traffic of multiple VLANs over a single link and allow you to extend VLANs across an entire network. All Layer 2 switching ports maintain MAC address tables.
How do you create an inter VLAN routing?
- Step 1: Create VLANs (VLANs 10 and 20) on the L2 switch. Description.
- Step 2: Assign the VLANs to the L2 switch ports.
- Step 3: Enable L3 routing and create VLANs (VLANs 10 and 20) on the L3 switch.
- Step 4: Configure Switch VLAN Interfaces (SVI)
- Step 5: Configure a routed port for connecting to the firewall on the L3 switch.
How many maximum VLAN we can create on Cisco L2 switch?
The switch must be in VTP transparent mode when you create VLAN IDs from 1006 to 4094. Although the switch supports a total of 255 (normal range and extended range) VLANs, the number of configured features affects the use of the switch hardware.
