2. (7 points) Routing and forwarding are the two key functions of the Network layer. What is the purpose of each (pick one)? i. Routing puts incoming packets to outgoing ports; forwarding calculates shortest paths. ii. Routing calculates shortest paths; forwarding puts incoming packets to outgoing ports ii. Routing and forwarding are the same iv. Routing operates at the Network layer, while forwarding at the Data Link Layer ******** 3. [8 points] Consider the following forwarding table. Indicate which outbound interface will be selected for each of the packets below the table. Destination Address Range Link interface 11001000 00010111 0001**** 0 11001000 00010111 00011000 11001000 00010111 00011*** ******* otherwise Packet 1 with Destination Address 11001000 00010111 00010110 10100001 goes to outbound interface ******* 1 2 3 Packet 2 with Destination Address 11001000 00010111 00011000 10101010 goes to outbound interface
