Computer Networks

1. Use picture above to answer these questions, if A, B, C, and D (3^rd octet) are as follow:
   1. A=36
   2. B=A+1
   3. C=A+2
   4. D=A+3
   5. x1, y1, z1 are interface for gateway router, while x2, x3, y2, y3, z2, z3 are for interface router.

1. Specify routing table R1, R2, and R3, using this table!

Destination	Next hop	Interface

2. With the Routing Table you have made, specify from point a, which path will PC1B follow when communicating with PC2B and PC3B!
3. From theory, there is a routing table Network Address 0.0.0.0 with Subnet Mask 0.0.0.0, explain the functionality of this routing table!
4. Does the network in picture 1 need routing in point c? Why?

P.S:

- Please answer in a proper format - Please answer in a typed or softcopy format - Please don't do it with pen or pencil, do it with software or tools - If you want to ask any question, ask it in the comment section, I will try to answer it

Thanks!
