Objectives:
• Configure a local user account on R1 and configure authenticate on the console and vty lines using local AAA.
• Verify local AAA authentication from the R1 console and the PC-A client.
• Configure server-based AAA authentication using TACACS+.
• Verify server-based AAA authentication from the PC-B client.
• Configure server-based AAA authentication using RADIUS.
• Verify server-based AAA authentication from the PC-C client.
Background / Scenario:
The network topology shows routers R1, R2 and R3. Currently, all administrative security is based on knowledge of the enable secret password. Your task is to configure and test local and server-based AAA solutions.
You will create a local user account and configure local AAA on router R1 to test the console and vty logins. o User account: Admin1 and password admin1pa55
You will then configure router R2 to support server-based authentication using the TACACS+ protocol. The TACACS+ server has been pre-configured with the following:
o Client: R2 using the keyword tacacspa55 o User account: Admin2 and password admin2pa55
Finally, you will configure router R3 to support server-based authentication using the RADIUS protocol. The RADIUS server has been pre-configured with the following:
o Client: R3 using the keyword radiuspa55 o User account: Admin3 and password admin3pa55
The routers have also been pre-configured with the following:
o Enable secret password: ciscoenpa55
o OSPF routing protocol with MD5 authentication using password: MD5pa55
Note: The console and vty lines have not been pre-configured.
Note: IOS version 15.3 uses SCRYPT as a secure encryption hashing algorithm; however, the IOS version that is currently supported in Packet Tracer uses MD5. Always use the most secure option available on your equipment.
