High-Level Design (HLD):

Conduct an initial assessment of the existing network infrastructure.
Define the overall network architecture for Sandoz site, including network segmentation, connectivity, and security.
Identify and document network components, including routers, switches, firewalls, and any necessary network services.
Specify network protocols and standards to be used.
Create a network topology diagram.
Define high-level security measures and access controls for the separated networks.
Identify any redundancy and failover mechanisms required.

Low-Level Design (LLD):

Provide detailed technical specifications for network components, including hardware models, configurations, and settings.
Create detailed network diagrams for Sandoz sites, specifying the placement of devices and connections.
Specify IP addressing schemes for sites.
Define routing and switching configurations, including VLANs and routing protocols.
Detail firewall rules, security policies, and encryption mechanisms.
Specify redundancy and recovery.
Identify any monitoring and management tools to be used.

Documentation:
