VLAN tagging using 802.1Q protocol.
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.
all VLANs
Network engineers value VLANs for their flexibility. They can include ports from more than one switch or segment. Any type of node can belong to one or more VLANs.
By default, all defined VLANs are allowed on the trunk.
All configured VLANs will be allowed across the trunk.

Although VLANs and subnets are quite different concepts, when using VLANs, there should be a one-to-one correspondence between the two. That is, every VLAN should be in a different subnet.Although VLANs and subnets are quite different concepts, when using VLANs, there should be a one-to-one correspondence between the two.

A trunk port is a port on a switch that can be assigned to carry multiple VLANs across switches or increase overall bandwidth/throughput.

When configuring a trunk between two switches, two key options to consider are the trunking protocol and the encapsulation type. The most common trunking protocols are IEEE 802.1Q and Cisco's proprietary ISL (Inter-Switch Link), with 802.1Q being the widely accepted standard. Additionally, it's important to ensure that both switches are configured to allow the same VLANs across the trunk, which can involve specifying allowed VLANs or setting the trunk to carry all VLANs by default.
- To restrict traffic on specified trunk lines.Explanation: By default all the VLANs that exist on a switch are active on a trunk link. VTP pruning allows the switch to not forward user traffic for VLANs that are not active on a remote switch. This feature dynamically prunes unneeded traffic across trunk links. If the VLAN traffic is needed at a later date, VTP will dynamically add the VLAN back to the trunk.-Rocky

Yes, Cisco Layer 2 switches support VLANs (Virtual Local Area Networks). VLANs allow network segmentation by creating separate broadcast domains within the same physical network infrastructure. This capability enhances network performance and security by isolating traffic among different groups of users or devices. Cisco's implementation of VLANs follows the IEEE 802.1Q standard, enabling the tagging of Ethernet frames for proper routing between VLANs.
