In the context of wireless network design, documentation is typically divided into two primary categories: High-Level Design (HLD) and Low-Level Design (LLD).

High-Level Design (HLD):Provides an overview of the network architecture, including major components and their relationships. It focuses on the overall design without delving into specific configurations.

Low-Level Design (LLD):Offers detailed information about the network, including specific configurations, IP addressing schemes, VLAN assignments, and device roles.

When documenting VLANs, the LLD should include a table that specifies which devices perform routing services for each VLAN. This level of detail ensures that during implementation, network engineers have clear guidance on how to configure each device to handle inter-VLAN routing appropriately.
