What are the functions of BGP MD5 authentication on S series switches

Q: What are the functions of BGP MD5 authentication, and the simple and cipher parameters?
A: BGP MD5 authentication is designed to prevent TCP attacks. The MD5 password and TCP+BGP packets are input for calculation and then result A is saved in a TCP packet. The TCP peer resolves the result to check whether the TCP packet is a fake one. If so, it discards this TCP packet to guarantee stable TCP connection.
The simple and cipher parameters only determine in which mode a password is displayed.
If the simple parameter is configured, the password is displayed in plain text.
If the cipher parameter is configured, the password is displayed in cipher text.
If the same password is configured on both ends, the two ends adopt the same password for communication.
