Impact on the System

If a TCP connection fails to be established, the upper-layer routing protocols such as LDP or BGP cannot set up sessions.

Possible Causes

Cause 1: The MD5 passwords configured for the local and peer TCP ports did not match each other.

Cause 2: An MD5 password was configured only for one TCP port.

Procedure

  1. Run the display current-configuration command on both ends to view whether the MD5 passwords are configured for the TCP connection.

    • If an MD5 password is configured only for one TCP port, configure the same MD5 password for the end that does not have one.If MD5 authentication fails, go to Step 3.

    • If the MD5 passwords configured for the TCP ports are different, go to Step 2.

  2. Reconfigure the MD5 passwords to the same value.
  3. Collect the alarm, log, and configuration information, and contact technical support personnel.
  4. End.
