Task: Configure SSH on Router R2

Router 1

R1(config)#interface fastEthernet 0/0

R1(config-if)#ip address

R1(config-if)#no shutdown 

Router 3

R3(config)#int fastEthernet 0/0

R3(config-if)#ip address

R3(config-if)#no shutdown

Router 2

R2(config)#int fastEthernet 0/0

R2(config-if)#ip address

R2(config-if)#no shutdown 


R2(config)#int fastEthernet 0/1

R2(config-if)#ip address

R2(config-if)#no shutdown 

Step 1: Set router parameters

R2(config)#ip domain-name

Step 2: Generate Asymmetric Keys

R2(config)#crypto key generate rsa 

The name for the keys will be:

Choose the size of the key modulus in the range of 360 to 2048 for your

  General Purpose Keys. Choosing a key modulus greater than 512 may take

  a few minutes.


How many bits in the modulus [512]: 

% Generating 512 bit RSA keys, keys will be non-exportable...[OK]

Step 3: Configure SSH timeouts and username

R2(config)#ip ssh time-out 15

R2(config)#ip ssh authentication-retries 2

R2(config)#username student password cisco

Step 4: Configure local authentication and vty

R2(config)#line vty 0 4

R2(config-line)#transport input ssh 

R2(config-line)#login local 

Verify SSH running

R1#ssh -l student







R3#ssh -l student

    things are very interesting here,the topology itself and the configurations are so accurate,well and simpler explained!
