Mar 27, 2017 RSA keys are generated in pairs—one public RSA key and one private RSA key. If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys. Note Before issuing this command, ensure that your router has a hostname and IP domain name configured (with the hostname and ip domain-name commands). Now we can generate the RSA keypair: R1(config)# crypto key generate rsa The name for the keys will be: R1.NETWORKLESSONS.LOCAL Choose the size of the key modulus in the range of 360 to 4096 for your General Purpose Keys.
