Hello,

Please p***eed as follow

Click the target NE in the NE Explorer. Choose Configuration > Control Plane Configuration > IGP-ISIS Configuration from the function tree. Click the Port Configuration tab.
Check the four NNI GE optical ports though which the NE02 interconnects with NE03 and NE03 interconnects with NE04. It is detected that all the ports are added to the Port list. This indicates that the ISIS protocol at these ports is enabled.
According to the NE planning, it is detected that the IP addresses of the NNI Ethernet optical interfaces of NE02, NE03, and NE04 are correctly set and in the same network segment.
Check NE03 on site according to the NE planning table. It is detected that the fiber which should be inserted to port 1 is incorrectly inserted to port 2, and the fiber which should be inserted to port 2 is incorrectly inserted to port 1.
After the fiber connections at ports are corrected, configure the LDP peers again. In this case, the configuration is successful.

Thanks
