Explanation:
1. Internal network:
A network that does not utilize any uplink ports and is used for communication between servers in the same frame.
2. Tagged network:
A network that contains multiple networks on a single uplink set that allows your customer to share uplinks with those networks.
3. Tunnel network:
A network with a dedicated set of uplink ports used to pass a group of VLANs without changing the VLAN tags.
4. Untagged network:
A network in which any tagged packets are dropped, and forwarding is done by a MAC address.
Internal networks: Used for intra-frame communication without external connectivity.
Tagged networks: Enable VLAN tagging to share uplinks across multiple networks.
Tunnel networks: Preserve VLAN tags while passing them through uplinks to external systems.
Untagged networks: Do not use VLAN tagging; they rely on MAC address-based communication.
