針對國別調整BGP優先權
一、先用https://ipinfo.io/countries/cn 找出要調整的國家的全部AS Number，將這些AS Number做利用正規化表示法設定成一組國別清單

Enable SSHv2 on Cisco Router & Switch
Steps to enable SSHv2 on Cisco Router & Switch
1. Define the hostname
2. configure the domain name
3. Specifies the RSA key pair to use for using SSH.
R2(config)#ip ssh rsa key-pair name {key-pair name}
By doing so SSH version 1.5 is deactivated
4. For SSH Version 2, the modulus size must be at least 768 bits.
R2(config)# crypto key generate rsa usage-keys label {keypair-name} modulus 768
4. Enable SSH version 2
5. Check the version with "show ip ssh"
