Router#conf t

Router(config)#hostname vOS-I

Generating RSA key  (selagi takde key, ssh port tak enable)

R1 (config)#  ip domain-name firewall.cx
R1(config)# crypto key generate rsa 
The name for the keys will be: R1.firewall.cx
Choose the size of the key modulus in the range of 360 to 4096 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes.                                                                                                                                                                                                     How many bits in the modulus [512]: 4096
% Generating 4096 bit RSA keys, keys will be non-exportable...
[OK] (elapsed time was 183 seconds)
