In This Tutorial We Are Going To Learn How To Configure Radius Server  Authentication In Cisco Packet Tracer With Telnet

Q-1 Now What Is Radius ?

Ans- Radius is a widely implemented networking protocol sometimes referred to as a client/server protocol, which provides a centralized mechanism of administering user account information. These can be usernames, passwords and privilege levels for each account.

Now Firstly Open A Cisco Packet Tracer And Here I Am Showing You The Cennerio Of The Radius Server    With The Router,Pc,Switch, With The Radius Server

Now Firstly Assign The Ip Address To The Pc And The Server

Now Go To The Terminal Of Router And Assign The Ip Address To The Pc And Server

Configuration On Router 1

Router>enable

Router#config t

R1(config)#int fa0/0

R1(config-if)#ip address 1.0.0.1 255.255.255.0

R1(config-if)#no shut

R1(config-if)#

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

R1(config-if)#exit

R1(config)#int fa0/1

R1(config-if)#ip address 2.0.0.1 255.255.255.0

R1(config-if)#no shut

R1(config-if)#

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

R1(config-if)#exit

R1(config)#

This Is All How We Assign The Ip Address To The Server And The Pc Through Router Now We Have To Do The Configuration Of Radius Server

Now Go To The Server And Click On Services And Then Clic AAA And Then On The Services

Now See In This Digram What We Have To Do The Configuration In The Radius Server Services

After This Now We Have To Do The AAA Authentication Configuration On The Router

AAA Authentication Configuration On Router 1

R1(config)#aaa new-model

R1(config)#radius-server host 2.0.0.2 key redhat

R1(config)#aaa authentication login default group radius local

R1(config)#line vty 0 5

R1(config-line)#login authentication default

R1(config-line)#

This Is All What Configuration We Have To Do For The Radius Server

Now Go To The Pc And Click On Terminal And Do Telnet

PC>telnet 2.0.0.1

Trying 2.0.0.1 …Open

User Access Verification

Username: root
