In traditional inter-VLAN routing, bandwidth is typically limited by the routing device's capacity and the physical connection between switches and routers. Each VLAN operates as a separate broadcast domain, and routing between them requires the router to process traffic, which can create a bottleneck if the router or interconnecting link is not adequately provisioned. The overall bandwidth can also be influenced by the type of routing (e.g., software vs. hardware) and the number of VLANs being routed simultaneously. Ensuring sufficient bandwidth often involves using faster routers or Layer 3 switches to manage inter-VLAN traffic efficiently.

Which network virtualization technique enables two virtual LANs (VLANs) at two different sites to connect to each other over a WAN?
The network virtualization technique that enables two virtual LANs (VLANs) at different sites to connect over a WAN is known as Virtual Private LAN Service (VPLS). VPLS uses MPLS (Multiprotocol Label Switching) to create a virtualized Ethernet network, allowing geographically dispersed VLANs to function as if they were on the same local network. This technique provides seamless connectivity and allows for efficient communication between the VLANs across the WAN.
Does a low bandwidth signal have more power than a high bandwidth signal?
A low bandwidth signal does not have more power.
What is the general purpose of a bandwidth meter?
It measures the bandwidth, or amount of data, which a user has used. This is useful for companies which have limits to the amount of bandwidth they have sold, or who sell bandwidth at a price per gigabyte.
What happen if the bandwidth of signal greater than channel bandwidth?

Where can one measure how much bandwidth they are using?
A simple search of the net will find there are many bandwidth monitoring sites that are available for free. A popular one is callled Free Meter Bandwidth Meter. You also can use WFilter freeware for network bandwidth monitoring.
Why would a VLAN benefit from trunking?
VLANs benefit from trunking because it allows multiple VLANs to be transmitted over a single physical link between switches, optimizing bandwidth usage and reducing the number of required connections. Trunking ensures that traffic from different VLANs remains segregated while still being able to traverse the same network infrastructure. This capability enhances network scalability, simplifies management, and improves efficiency by minimizing the number of physical links needed for inter-VLAN communication.
What is a trunk Port?
A trunk port is a port on a switch that can be assigned to carry multiple VLANs across switches or increase overall bandwidth/throughput.
How many physical interfaces are required to perform inter-VLAN routing with traditional inter-VLAN routing?
Traditional inter-VLAN routing using physical interfaces does have a limitation. As the number of VLANs increases on the network, the physical approach of having one-router-interface-per-VLAN quickly becomes hindered by the physical hardware limitations of a router.Lewis, Wayne (2008-04-28).

What is traditional inter vlan routing?
Traditional inter-VLAN routing involves using a router to enable communication between different VLANs (Virtual Local Area Networks). Each VLAN is assigned its own subnet, and the router interfaces with each VLAN through sub-interfaces or physical interfaces. This method allows for the separation of broadcast domains while facilitating inter-VLAN traffic, enhancing network performance and security. Typically, this approach requires a router or a Layer 3 switch to manage the routing process.
What is a router on stick inter vlan routing?
A physical router device with an interface that routes between two or more VLANs that are attached to a VLAN network segment by a trunk link. In other words a " router on a [ TRUNK ] " which is originating from switches with independent non routing VLANs.
What benefit will configuring VLANs provide to the current configuration?
Configuring VLANs (Virtual Local Area Networks) will enhance network segmentation, improving security and performance by isolating traffic within each VLAN. This separation reduces broadcast traffic and increases overall bandwidth efficiency, as devices in different VLANs do not interfere with one another. Additionally, VLANs simplify network management, allowing for easier monitoring and control of traffic flows, and enabling tailored policies for different user groups or departments.
What is the difference between vlan and inter-vlan?
VLAN is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. Inter VLAN is defined as two VLANS connected to each other and communicating.
How do you program vlans on a switch?

Advantages and disadvantages of inter-vlan routing?
Advantages are that it is simple to implement, A Layer-3 switch (expensive) is not required, The router provides communication between VLANs.
What distinguishes traditional routing from router-on-a-stick?
Router on a stick usually just routes between VLANs and has only 1 actual interface.
Which scalable method must be implemented in order to provide inter-VLAN routing on a switched network with more than 1000 VLANs?
To provide inter-VLAN routing in a scalable manner for a switched network with over 1000 VLANs, you should implement Layer 3 switches with Virtual Routing and Forwarding (VRF) technology. This allows for the creation of multiple virtual routing tables within the same device, enabling efficient routing between VLANs without overwhelming a single routing instance. Additionally, using techniques like VLAN trunking and Spanning Tree Protocol (STP) can help manage the traffic effectively across the network.
