Enabling MD5 authentication for TCP connection establishment

To enhance MSDP security, enable MD5 authentication for both MSDP peers to establish a TCP connection. If the MD5 authentication fails, the TCP connection cannot be established.

Configure the same authentication method and key for the MSDP peers involved in MD5 authentication to avoid authentication and TCP connection failures.

1. Enter system view.

   system-view

2. Enter MSDP view.

   msdp [ vpn-instance vpn-instance-name ]

3. Configure the device to perform MD5 authentication when establishing a TCP connection with an MSDP peer.

   peer peer-address password { cipher | simple } password

   By default, the device does not perform MD5 authentication when establishing a TCP connection with an MSDP peer.
