Chapter 1 MPLS Basics Configuration Commands
& Note:
l Except for the LDP GR feature, all commands in MPLS LDP view are available in MPLS LDP VPN instance view. The difference is that the commands serves the public network LDP in MPLS LDP view but serves the MPLS LDP VPN instance in MPLS LDP VPN instance view.
l For information about GR commands, refer to GR Commands in System Volume.

Use the debugging mpls ldp command to enable debugging for LDP.
Use the undo debugging mpls ldp command to disable debugging for LDP.
By default, debugging is disabled for LDP.
Examples
# Enable LDP advertisement event debugging by executing the debugging mpls ldp advertisement command
Start two switches, connect the two switches, and configure MPLS and MPLS LDP for them to establish a session between them. Enable LDP advertisement event debugging by executing the debugging mpls ldp advertisement command on one switch while restarting LDP on the other switch.

1.1.2 debugging mpls lfib
Syntax
debugging mpls lfib [ code | sync ]
undo debugging mpls lfib [ code | sync ]
View
User view
Default Level
2: System level
Parameters
code: Enables debugging for MPLS entry encoding and decoding.
sync: Enables debugging for MPLS entry synchronization.
Description
Use the debugging mpls lfib command to enable debugging for MPLS entry synchronization or encoding and decoding.
Use the undo debugging mpls lfib command to disable debugging for MPLS entry synchronization or encoding and decoding.
By default, the debugging for MPLS entry synchronization and encoding/decoding is disabled.
Caution:
l Do not enable debugging for MPLS entry encoding and decoding when there are a large number of entries to be sent. Otherwise, there will be large amounts of command output information, affecting the normal operation of the system.
l The output debugging information for encoding is from the main board, and that for decoding is from the interface board and the backup main board.
