BGP MD5 authentication is designed to prevent TCP attacks. When the MD5 algorithm is adopted, the MD5 password and TCP+BGP packets are input for calculation and then result A is saved in the 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 parameter and cipher parameter only determine in which mode a password is displayed.
For the simple parameter, the password is displayed in the plain text.
For the cipher parameter, the password is displayed in the cipher text.
If the same password is configured on both ends, the two ends adopt the same password during interworking.
