(10 points) - B is a bridge with an initially empty filtering table, while R is an IP router - H1, H2, H3, H4, H5 and H6 are hosts - I1, I2, I3, I4, I5, I6, I7 and I8 are 32-bit IP (interface) addresses - E1, E2, E3, E4, E5, E5, E6, E7, E8, E9 and E10 are 48-bit Ethernet (MAC) addresses - N1, N2 and N3 are local networks Suppose host H3 sends an IP packet (encapsulated in Ethernet frame) to host H6. (a) What are the frame and packet header contents (source and destination Ethernet and IP addresses) as it traverses through N2 ? ( 2 points) (b) What are the frame and packet header contents (source and destination Ethernet and IP addresses) as it traverses through N3? (2 points) (c) Will bridge B send a copy of the any of the following frames to N1? (2 points) (i) Original frame sent by H3 (ii) Response frame sent by H6 as a reply to the original frame sent by H3 (d) If H3 sends a packet to H4 instead of H6. Will Router R forward the packet to N3? (1 point) (e) List the uses of the Ethernet address and IP address. (1 point) (f) List the differences between Hub, Repeater, Bridge and Switch. (2 points)
