- Forwards a packet to all outgoing links
- Forwards a packet to the next free outgoing link
- Determines on which outgoing link a packet is to be forwarded
- Forwards a packet to all outgoing links except the originated link
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
A router is a networking device responsible for directing data packets between networks.
Step 1: Role of router Routers connect multiple networks and manage traffic between them.
Step 2: Packet forwarding When a packet arrives, router examines destination IP address.
Step 3: Routing table Router uses routing table to decide best path.
Step 4: Decision making It determines the most appropriate outgoing link for forwarding.
Step 5: Conclusion \[ \boxed{\text{Determines outgoing link for packet}} \]
Final Answer: \[ \boxed{(C)} \]
