Consider a router that interconnects subnets A$,$ B and C$,$ as shown in the figure below. Suppose all of the interfaces in each of these three subnets are required to have the prefix $195\mathrm{.}251\mathrm{.}252/24($i$.$e$.$ a $/24$ CIDR portion of the IP space is provided$).$ Also suppose that Subnet A is required to support $100$ interfaces, Subnet B is required to support $60$ interfaces, and Subnet C is required to support $50$ interfaces.
