LAN Network Topology Image

Use the image as a reference, if the values are A, B, C and D (3rd octet) with the following conditions:

• Value A = the number of each digit of your number (the number of each digit is 29)
• Value B = A + 1
• Value C = A + 2
• Value D = A + 3
• x1, y1, z1 are the interfaces for the router gateway, while x2, x3, y2, y3, z2, z3 are for the router interface

a. Find the Routing Table R1, R2, and R3 using the following table!

Destination	Next hop	Interface

b. With the Routing Table that you have specified in point a, which path will PC1B take when communicating with PC2B and PC3B

c. In theory there is a routing table for Network Address 0.0.0.0 with a Subnet Mask of 0.0.0.0, explain the function of this routing table?

d. Does the image network require routing at point c? Why?
