You are required to configure a network with the following parameters: 1. Configure two routers, Hub1 and Hub2, that have the function of Backbone routers. Hub1 and Hub2 connect to each other with 2 FastEthernet connections. The connections between the Hub1 and Hub2 Router will be configured using a Class A RFC 1918 Private Addressing. The choice of subnet and subnet mask must be made while maximizing the use of IP addresses. Define: a. Subnet and subnet mask for Link 1 and Link 2 between Hub1 and Hub2. b. The number of hosts available on each subnet. c. The IP address for each interface. 2. Configuring the Site1 router, which is a router connected to the Hub1 router. Site1 has an internal network and uses a Class C Private Addressing You must use a Publicly addressed subnet between Hub1 and Site1. The choice of subnet and subnet mask should be made while maximizing the use of IP addresses. Define: a. Subnet and subnet mask for the connection between Hub1 and Site 1. b. The number of hosts available on each subnet. C. The IP address for each interface. d. IP address for a host and default gateway for the internal network. 3. Configuring the Site2 router, which is a router connected to the Hub2 router. Site2 has an internal network and uses a Class B Private addressing. You must use a Publicly addressed subnet between Hub2 and Site2. The choice of subnet and subnet mask should be performed while maximizing the use of IP addresses. Define: a. Subnet and subnet mask for the connection between Hub2 and Site2. b. The number of hosts available on each subnet. c. The IP address for each interface. d. IP address for a host and default gateway for the internal network 4. Configure the OSPF routing protocol between routers Hub1, Hub2, Site 1, and Site2. Sitel's internal network must communicate with Site2's internal network
