VLAN Trunk Links | Network Fundamentals Part 13

Switch Trunk Links | Network Fundamentals Part 13 We’ve seen that VLANs can divide up a switch into separate logical networks. But what happens when we run out of ports? We need to buy a new switch. But how do we connect the two switches in a VLAN-aware network? Do we need a separate link for each VLAN? That could work, but won’t scale well. What if we have 50 VLANs? Instead, we can use a trunk link. This uses a process called tagging, where the VLAN ID is added to each frame, in the form of a small tag in the ethernet header. Now a single link can be used between the switches, and traffic from different VLANs can pass over it, all while still keeping the traffic separate. There are a few special VLANs which work with this. One of these is VLAN 1, which is used for switch-to-switch control traffic (for example, CDP or LLDP). Another is the native VLAN, which enables non-VLAN aware devices to connect. Trunking also enables extra features, like Router On A Stick, or ROAS. This is where a router can connect to the network using a single trunk link, and forward traffic between VLANs. See how all of this works in this video! Lab: https://networkdirection.net/labsandq...
