A large corporation owning IP address range of 192.168.2.0/25 has its own ISP. Assume that an office building within the corporation using address range of 192.168.2.0/28 desires a connection with its own autonomous ISP in addition to the connection with its corporation. The building is connected to corporation edge router R1 through its edge router R2, and is also connected to its own ISP through R3. We would like to configure connecting routers according to BGP. (a) Show the configuration of R1 and R2 and specifically demonstrate what R1 and R2 should advertise. (b) Repeat part (a) when the building management decides to have its own independent network IP addresses. (c) Show how routers should be configured if the corporation decides to use the building's ISP when it experiences slow bit rates during the peak traffic times.
