Thank you for sharing the videos in UA-cam good explanation. Can you please do videos on routing issues source to destination and destination to source,
The 802.1Q encapsulation (often abbreviated as Dot1Q) is used in routers and between switch to switch to enable VLAN tagging on trunk links. This allows multiple VLANs to share the same physical link while keeping their traffic separate and organized1. Note: trunk carries multiple VLAN. Here's a quick breakdown: On a Switch: When you configure a switch port as a trunk port using the encapsulation dot1Q command, it allows the port to carry traffic from multiple VLANs. The switch adds a VLAN tag to the Ethernet frames to identify which VLAN each frame belongs to. On a Router: When configuring a router interface as a sub-interface with encapsulation dot1Q, it allows the router to handle traffic from multiple VLANs over a single physical interface. This is often referred to as a "router on a stick" configuration. The router uses the VLAN tag to determine which VLAN the traffic belongs to and routes it accordingly. Without Dot1Q encapsulation, it's not possible to send multiple VLAN traffic over a single physical interface. Dot1Q is essential for tagging and identifying VLAN traffic, which allows different VLANs to share the same physical link while keeping their traffic separate and organized. Note: Without VLAN tagging, the switch or router wouldn't be able to distinguish between the different VLANs, and all traffic would be treated as part of the same broadcast domain.

Crystal clear explanation.... super sir
Thank you so much 🙂
Good explanation 😊
Glad you liked it. Thank You Brother
