Consider three subnets shown in Figure 2. Assume that they use the addresses assigned by Figure 3. (a) (3 points) E wants to send a data packet to F. Does router 1 receive this data frame sent from E? What are addresses of source IP, destination IP, source MAC and destination MAC of this data frame sent by E? A T LAN B Subnet 1 192.168.1.001 00-00-00-00-00-00 Router 1 D Figure 2: Three subnets, interconnected by routers.

LAN F F (b) (3 points) E wants to send a data packet to B. Does router 1 receive this data frame sent from E? What are addresses of source IP, destination IP, source MAC and destination MAC of this data frame sent by E? How many data frames (at least) are needed so that B will receive the datagram from E? I at C? (d) (2 points) what nodes (out of A, B, C, D... I, S1, S2, S3, S4) will physically receive the frame I C? (e) (2 points) what nodes (out of A, B, C, D ... I, S1, S2, S3, S4) will physically receive the frame F C?
