Hello, I have a question:

The two ends of an LSP are up and can send Hello Messages, but the peer end cannot receive them. Why?

Thanks

Hello,
If the two ends of an LSP are Up and can send Hello messages, but the peer end cannot receive the messages, the possible causes are as follows:
Devices do not support sending of large packets, for example, the device can send packets whose maximum size is 180 bytes. To check whether the peer end can send large packets, ping the IP address of the peer end using large packets.
Run the display cpu-defend statistics slot slot-id command to check whether Hello messages are dropped due to attack defense policies or Hello messages do not reach the cpu-defend module.
Check whether statistics on MPLS-related ACL packets exist and ACLs are correctly delivered.
Thanks
