F3215-HP Load Balancing Module Network Management Command Reference-6PW101

297
Parameters
group-name: Specifies the name of a peer group, a string of 1 to 47 characters.
ip-address: Specifies the IP address of a peer.
cipher: Specifies a ciphertext password.
simple: Specifies a plaintext password.
password: Password, a case-sensitive string of 1 to 137 characters in cipher text, or 1 to 80 characters
in plain text.
Usage guidelines
You can enable MD5 authentication to enhance security in the following ways:
• 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 packets to avoid modification to the encapsulated BGP packets.
For secrecy, all passwords, including passwords configured in plain text, are saved in cipher text.
Examples
# In BGP view, perform MD5 authentication on the TCP connection set up between the local router
10 .1.10 0 .1 a n d t h e p e e r r o u t e r 10 .1.10 0 . 2.
