1. SSH（stelnet）配置。

[R1] rsa local-key-pair create #生成一个加密秘钥。

The key name will be: Host

% RSA keys defined for Host already exist.

Confirm to replace them? (y/n)[n]:y

The range of public key size is (512 ~ 2048).

NOTES: If the key modulus is greater than 512,

It will take a few minutes.

Input the bits in the modulus[default = 512]:1024
