Example Concept: In a multi-site network, VLANs should be designed to reflect the organizational structure and traffic patterns. This typically involves creating VLANs based on function (e.g., HR, Finance, IT), geography (e.g., Site A, Site B), or security level (e.g., public, private). Use consistent VLAN IDs across sites to simplify management and troubleshooting. Implement VLAN trunking protocols like 802.1Q to allow VLAN traffic to traverse between switches and sites efficiently. Ensure proper VLAN segmentation to limit broadcast traffic and enhance security by isolating different types of traffic.
