Which are three options for inter-VLAN routing?

There are three inter-VLAN routing options:

• Legacy Inter-VLAN routing: This is a legacy solution.
• Router-on-a-Stick: This is an acceptable solution for a small- to medium-sized network.
• Layer 3 switch using switched virtual interfaces (SVIs): This is the most scalable solution for medium to large organizations.

What does Inter-VLAN routing separate?

Definition. Inter-VLAN routing can be defined as a way to forward traffic between different VLAN by implementing a router in the network. The user nodes in the VLANs forwards traffic to the router which then forwards the traffic to the destination network regardless of the VLAN configured on the switch.

Can one VLAN access another VLAN?

In a properly designed IP network, a VLAN should map to a single broadcast domain, which should map to a unique IP network. For ease of troubleshooting (and for avoiding trouble!), traffic from one VLAN should not reach another VLAN without an OSI Layer 3 device, such as a router.

What is the purpose of inter-VLAN routing?

VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On Catalyst switches it is accomplished by the creation of Layer 3 interfaces (switch virtual interfaces (SVIs) ).

What do I need to know about setting up VLANs?

Choose a valid VLAN number.

Choose a private IP address range for devices on that VLAN to use.

the administrator assigns a VLAN number to each switch port.

Configure routing between VLANs as needed.

How useful is a layer 3 switch for network routing?

Support routing between virtual LANs.

Improve fault isolation.

Simplify security management.

Reduce broadcast traffic volumes.

as a separate router isn’t required between each VLAN.

segregate traffic better.

How do VLANs work?

Virtual Local Area Networks (VLANs) separate an existing physical network into multiple logical networks. Thus, each VLAN creates its own broadcast domain. Communication between two VLANs can only occur through a router that is connected to both. VLANs work as though they are created using independent switches.

What is VLAN configuration?

Vlan – Configuration. A Virtual LAN (Vlan) is a logical grouping of hosts on a layer 2 network that may or may not be on the same switch or network segment.
