Scenario
In this topology you should assign IP address as we noted in topology. After IP address was configured successfully,
you may configure one of dynamic routing protocol ( we suggest you use OSPF v2 to configure routing in this
scenario). First, You may verify connectivity by ping from one of PCs to all PCs and Sever to make sure routing that
you configure is working properly. Second, you should configure this scenario by 2 following task:
Task 1
Configure IP address to all end devices and routers as we mention in topology (we suggest you to assign IP
x.x.x.10 to all PCs)
Configure HTTP, DNS and FTP server (domain name should use www.cisco.com for DNS mapping)
Configure dynamic routing protocol (recommend for OSPF v2)
Note: After you configure HTTP, DNS, FTP Server and routing successfully, you should access web server from Guest
PC by using web browser to www.cisco.com. Accessing should be successfully.
Task 2
Create extended ACL by using number 100
Create statements that compliance with
Guest Network should not reach Server Host by request HTTP
Guest Network should reach all service and network except upon case
Apply ACL to which interface should be
