LDP/4/OPENRETRYTMR:When the interface [interface-name] cannot join the multicast group, the retry timer was opened.
When the interface failed to add to the multicast group, the reconnection timer was restarted.
1: Incorrect configurations of the interface that applies for adding to the multicast group resulted in failing to add to the multicast group. Restarted the timer that added to the multicast group. The precondition was that the interval of the timer did not exceed the maximum interval.
2: The invalid ID of the instance that applies for adding to the multicast group resulted in failing to add to the multicast group. Restarted the timer that added to the multicast group. The precondition was that the interval of the timer did not exceed the maximum interval.
