Options
- AARP
- BCDP
- Cflooding
- Dmulticast
Explanation
The technical term for the process where a switch forwards a frame out of all interfaces except the interface that received the frame is called "flooding" or "broadcast flooding." When a switch receives a frame with an unknown destination MAC address, it needs to determine which port to forward the frame to. If the switch does not have an entry for the destination MAC address in its MAC address table (also known as the CAM table or MAC forwarding table), it cannot make a forwarding decision based on the destination MAC address. In such cases, the switch performs flooding by forwarding the frame out of all active interfaces, except the interface from which the frame was received. This ensures that the frame reaches all other devices connected to the switch. By flooding the frame, the switch maximizes the chances of the frame reaching the correct destination and prevents the possibility of dropping the frame due to insufficient information about the destination.
