As a network administrator for a company‚ you want to configure an IP route between two routers. Of static and dynamic routing‚ which is more appropriate? Explain your answer in 200 to 300 words. I think that the best routing choice for this would be a static IP; this is because for a company you may want to have the ability to check the log for problems. Using a dynamic IP would mean that the people that logged on to their device would be almost invisible because they could

Assignment 2: LAN with Two Subnets Gabriel Jerez Strayer University: Asynchronous CIS408: Network Infrastructure Planning October 28‚ 2012 A LAN consisting of two subnets with a total of 50 users‚ each subnet consisting of 25 users‚ a domain controller‚ and a switch must be connected using the appropriate networking equipment. In my design I decided to use a Cisco 2900 Series Router to connect the two subnets (Cisco ‚ 2012). The router has both routing

Layer 2 Domains Paper Layer 2 Domains Paper We have chosen an extended star topology connection using a router to designate the VLANS and two 24 port switches to provide the most cost effective setup for this small office network. Being the very small nature of the setup we are using a class C network of 192.168.0.1 that we will designate the first 20 IP addresses of each VLAN as static to support any servers we might install as well as printers we may install in the future.
