IP Switching
IP Switching (or packet forwarding) encompasses tasks required to
forward packets for both Layer 2 and Layer 3, as well as traditional routing.
These functions include:
• Layer 2 forwarding (switching) based on the Layer 2 destination MAC
address
• Layer 3 forwarding (routing):
- Based on the Layer 3 destination address
- Replacing destination/source MAC addresses for each hop
- Incrementing the hop count
- Decrementing the time-to-live
- Verifying and recalculating the Layer 3 checksum
