Question

host host host S1 R1 S2 host host host subnet 1/2 subnet 3 3. KR, Ch. 6- P22 (slightly reworded with a modified figure). Consider the figure above for Problem 2. Provide MAC addresses and IP addresses for the interfaces at Host A, router R and Host F. Suppose Host A sends a datagram to Host F. Give the source and destination MAC addresses in the frame encapsulating this IP datagram as the frame is transmitted () from A to switch S1, (i) from Sl to router R1, (ii) from RlI to F. Also, give the source and destination IP addresses in the IP datagram encapsulated within the frame at each of these points in time.

Explanation / Answer

A to S1:
Source IP: Host A IP
Source MAC: Host A MAC
Destination IP: Host F IP
Destination MAC: Router R1 interface 1 MAC address

S1 to R1:
Source IP: Host A IP
Source MAC: Host A MAC
Destination IP: Host F IP
Destination MAC: Router R1 interface 1 MAC address

R1 to Host F:
Source IP: Host A IP
Source MAC: Router R1 interface 2 MAC address
Destination IP: Host F IP
Destination MAC: Host F MAC address

This is how the packet will travel...
