Area 0 Network: 192.168.49.0, which connects 2 other area networks:

Area 1 Network: 10.108.16.0-10.108.31.0

Area 2 Network: 10.108.32.0-10.108.47.0

If these networks were part of a classful IP addressing and routing architecture, then it would not be possible to advertise network area 1 and area 2 with a single statement, since they are both part of the only private class A IP space 10.0.0.0/8.

However, these two networks could be advertised by a number of network statements as part of a CIDR (classless inter domain routing) architecture.

What are the minimum number of network statements needed to advertise both network ranges and what are their CIDR designations?

E.g., we already know that 10.0.0.0/8 advertises the full range from 10.0.0.1 to 10.255.255.255 and is too broad, so the answer is not 1 statement, 10.0.0.0/8.

Hint: One of the CIDR addresses for area 2 is: 10.108.47.0/24, which can be used to advertise the 10.108.47.0 subnet of area 2 (from 10.108.47.0 to 10.108.47.255). But this approach for all of the subnets would require 32 statements, so the answer is greater than 1 and less than or equal to 32:).

You can use any tools available, including online CIDR calculators, but be sure and explain your proposed entries.
