Refer to the network figure above, showing two Ethernet Subnets connected through an IP Router, for questions #1, #2 and #3. For each device, both its Internet Protocol (IP) address and its MAC address (also called the Physical address or the Ethernet address) are shown. The Subnet Mask used by all devices is 255.255.255.192 (which is same as prefix length “/26”).
- (5 points) Assuming that Client #1 sent a packet to Client #3 and then Client #3 sent a packet back to Client #1 and NO other packets have been sent, show me the contents of the Forwarding Table (MAC Address Table) of the Ethernet Switch. There are 3 switch ports, named Fa0, Fa1 and Fa2. Your answer should show values for these 2 columns:
MAC Address Switch Port

2) IP and MAC addressing. True or False. One point for each correct answer, zero points for each incorrect answer. Many of the questions refer to the following network consisting of three 10Mbps Ethernet segments, one switch, and one router. Assume all ARP tables are up-to-date unless otherwise stated. a) Consider a network consisting of Ethernets, hubs, switches, and routers. Suppose one of the hubs is replaced with a switch. Then the network administrator must redefine some IP addresses. True...
