Consider the network shown below.  It includes two LANs (1 and 2) and three routers (A, B, and C) within an autonomous system.

   

What network should be advertised by Router A to Router C? This is the network for LAN 1.  The advertised network should be the smallest possible network that still enables routing to all interfaces in LAN 1. 

   

What network should be advertised by Router B to Router C?  This is the network for LAN 2.  The advertised network should be the smallest possible network that still enables routing to all interfaces in LAN 2. 

   

A single network should be advertised by Router C to the backbone. What is the smallest possible single network that can be advertised that still enables routing to all interfaces within the autonomous system?
