Suppose I want to send an IP datagram from node D to node C . Each step I also want to list the MAC addresses of the source and the destination , as well as the source and the destination of the IP datagram .
As a newcomer in networking and in efforts to understand how this would look like , I have came up with a solution which I would like you to criticize and give me pointers to further my knowledge.
Step 1 :
Ethernet(MAC) source : FD-0B-1F-63-32-88 ( MAC of D ) IP source : 128.119.109.251 ( IP of D )
Step 2 :
Ethernet(MAC) destination :FA-C3-3B-23-12-56 ( MAC of inner router) IP destination : 128.119.109.13 ( IP of C )
Step 3 :
Ethernet(MAC) source : FA-C3-3B-23-12-56 ( MAC of inner router) IP source : 128.119.109.251 ( IP of D )
Step 4 :
Ethernet(MAC) destination : C4-E6-48-38-CE-AF ( MAC of C ) IP destination : 128.119.109.13 ( IP of C )
Is my way of thinking correct in this situation?
Thanks in advance.
