Enabling MD5 Authentication for TCP Connections
BGP employs TCP as the transport protocol. To enhance security, you can configure BGP to perform
MD5 authentication when establishing a TCP connection. The two parties must have the same
password configured to establish TCP connections. BGP MD5 authentication is not for BGP packets,
but for TCP connections. If the authentication fails, no TCP connection can be established.
Follow these steps to enable MD5 authentication for TCP connections:
To do… Use the command… Remarks
Enter system view system-view —
Enter BGP view bgp as-number —
Enable MD5 authentication when
establishing a TCP connection to the
peer/peer group
peer { group-name |
ip-address } password { cipher

Follow these steps to configure BGP load balancing:
To do… Use the command… Remarks
