5. Consider the following network topology:

Assume the original routing table in D is as below.

Solution

Yes it will change.

From A we can reach z subnet through c router with 5 number of hopes.

If we check routing table in D, then we can reach z subnet through B router with 7 number of hopes.

Hence, through A we can reach z subnet with 6 number of hopes from router D.

Hence , 3rd row in D router will be changed

z             B                7

to

z            A                 6
