In this problem we have given the figure and in this figure we can say host a, this is host a and we can say this is host a is sending an ip packet to host b.
00:14
So this is sending ip packet through this path to host b.
00:20
Now we have to determine source ip address, destination ip address, source mac address and destination mac address of the ip packet.
00:29
First in case of say in the frame from host e so host e to this would be r2 now we can determine first this would be source ip address is here so this is source ip address so we can say source ip address and this is say 10 .168.
01:06
Point this would be point here.
01:12
10 .168.
01:13
This is 8 .10.
01:16
10 .98.
01:18
This is, let me write it more clearly.
01:20
So this is here.
01:23
10 .168.
01:28
10 .98.
01:30
Now, destination ip address is here.
01:35
So, destination ip address.
01:38
So we can say this would be.
01:41
Destination ip address and this is 10 .168 .11 .8 that is hot host b address as the destination now source mac address source make address is here so here we can say part 3 and this would be source mac address make address and this is say even so this would be a one even even even and so on so this is even even and then again even so this would be six times so this is even even and also even now destination make address so we can see this is the frame for from host a to r2 so we can say this is the frame for from host a to r2 so we can say this would be the destination mac address.
02:53
So here we can say destination mac address.
03:05
So this is for part 4 and this is b2, b2 up to 6 times.
03:11
So this would be b2, b2 and b2 and also b2.
03:20
So this is the right answer for part a.
03:23
And now we have to repeat it from r1 to host b.
03:28
So here r1 to host b.
03:30
So here we can say and now in the frame say for part b we have to do it again but in the frame of r1 to host b.
03:42
Now source ip address...
