Hands On Final
CNT150AA
Given:
200.0.0.0/24, subnet this setup so that all networks can work. There is one way out to the Internet and that is through the ISP (the Network number for that link is 177.43.33.76/30). Also configure passwords for network and console access. All PCs should be able to ping each other and they should send to the ISP any packets destined for other networks other than 200.0.0.0.x. Since the link through the border router is faster then the 64 K link, all traffic between New York and Chicago should go through the Border router. Use OSPF for routing within the 200.0.0.0 networks but don't use OSPF for 177.43.33.76.
