9. [10 points] Recall our discussion on IP and MAC addressing. Now consider the network diagram below. Let a packet start from Host A and travel through two routers to Host B. a. [4 points) Fill out the blank fields in the packet header at each traversed interface. (Note: no need to write down the whole MAC; just fill out the 6th byte) MP MP 1.1.1.2 3.3.3.2 MAC HAC MAC ME HAC PAC HAC MAC MAC А. du MAC MAC B HAC HAC 1.1.1.2 FF-FF-FF-FF-FF-55 3.3.3.2 FF-FF-FF-FF-FF-2A 2.2.2.1 FF-FF-FF-FF-FF-9B 3.3.3.1 FF-FF-FF-FF-FF-3A 1.1.1.3 FF-FF-FF-FF-FF-7D 1.1.1.1 FF-FF-FF-FF-FF-4B 2.2.2.2 FF-FF-FF-FF-FF-3B 3.3.3.3 FFFFFFFFFFFFFFF0F b.
