EGP authentication can prevent illegal routers from establishing neighbors with BCP routers. BCP authentication can be divided into MD5 authentication and Keychain authentication. Which of the following BGP messages will carry BCGP Keychain authentication information?

Answer options

Correct answer: A, B, C, D

Explanation

The correct answer is A, as the Open message is the initial message sent when establishing a BGP session and can carry Keychain authentication information.
