Which OSI layer header is rewritten with new addressing information by a router when forwarding between LAN segments?
- Layer 2
- Layer 3
- Layer 4
- Layer 7
Explanation: When a router forwards traffic between LAN segments it encapsulates the Layer 2 frame to determine the Layer 3 path. Once the Layer 3 path is determined, the router encapsulates the Layer 3 packet in a new Layer 2 frame with new Layer 2 addressing infomation for the destination LAN segment.
