**Consider Figure 1. Suppose A wants to send a packet to B.** **a. What destination MAC address should A indicate?** i. It's own MAC address ii. R's LAN-side MAC address E6-E9-00-17-BB-4B iii. R's WAN-side MAC address 1A-23-F9-CD-06-9B iv. B's MAC address 49-BD-D2-C7-56-2A *Figure 1: A network topology in which A wants to send a packet to B.* **b. Assume that A's ARP table is empty before it attempts to send a packet to B. What steps will A take in order to populate its ARP table and be able to craft the packet to B?** --- The diagram in Figure 1 illustrates a network topology comprising three main entities: - **A**: Represented by a computer icon, with two IP addresses, 111.111.111.111 (MAC: 74-29-9C-E8-FF-55) and 111.111.111.112 (MAC: CC-49-DE-00-AB-7D). - **R**: Denoted by a network router, bridging two networks with IPs 111.111.111.110 (MAC: E6-E9-00-17-BB-4B) on the LAN side, and 222.222.222.220 (MAC: 1A-23-F9-CD-06-9B) on the WAN side. - **B**: Depicted by a computer icon on the right, having IP addresses 222.222.222.222 (MAC: 49-BD-D2-C7-56-2A) and 222.222.222.221 (MAC: 88-B2-2F-54-1A-0F).
