Scenario: The routers at your company were configured by an inexperienced network engineer. Several errors in the configuration have resulted in connectivity and security issues. Your manager has asked you to re-design and document your work using your knowledge of networking, routing and security mechanism. Ensure that all routers are accessible only by authorized users and that your network should reach convergence.
Major Network Address – 193.30.1.0/24
LAN 1 – 62 hosts
LAN 2 – 10 hosts
LAN 3- 8 hosts
· Show the correct and complete IP Addressing Plan for the network. (1 pt- for each correct subnet address (NA). Total = 5 points
· LAN Configurations (3 pts- correct LAN configurations)
· WAN Configurations (3 pts - correct WAN configurations)
Total = 6 points
· Create a user ID of Admin1 with the highest possible privilege level with password netadmin1. (3 pts )
· Create a user ID of Admin2 with password netadmin2 with privilege level 2 with a customized privilege of accessing the global mode. (3 pts )
· Create a user ID of Admin3 with password netadmin3 with privilege level 10 with a customized privilege of accessing the running configuration file. (3 pts)
· All passwords should be encrypted. (2 pt)
· Create a Banner warning: “For Authorized Access Only” (2 pts)
· Idle router caused by inactivity should timeout in 10 seconds. (3 pts)
· For any 2 attempts in 10 seconds, all logins should be blocked for 1 minute. (3 pts)
Total = 19 points
The network 193.30.1.0/24 has 254 hosts.
Your subnets need 84 hosts.
