• Perform MD5 authentication when establishing TCP connections. Only the two parties that have the
same password configured can establish TCP connections.
• Perform MD5 calculation on TCP segments to avoid modification to the encapsulated BGP packets.
For security purposes, all passwords, including passwords configured in plain text, are saved in cipher
text.
Examples
# In BGP view, perform MD5 authentication on the TCP connection between the local router 10.1.100.1
and the peer router 10.1.100.2, and set the plaintext authentication password to aabbcc.
