The isis mpls ldp auto-config disable command disables MPLS LDP automatic configuration on an IS-IS interface.
The undo isis mpls ldp auto-config disable command restores the default configurations.
By default, if the mpls ldp auto-config command is run for an IS-IS process, MPLS LDP is enabled automatically on all interfaces which can establish IS-IS neighbor relationships in this IS-IS process; otherwise, MPLS LDP automatic configuration is disabled on these interfaces.

Usage Scenario
After the mpls ldp auto-config command is run for an IS-IS process, MPLS LDP is enabled automatically on all interfaces which can establish IS-IS neighbor relationships in the IS-IS process. If you want to disable MPLS LDP from an interface, run the isis mpls ldp auto-config disable command in the interface view.
Precautions
The isis mpls ldp auto-config disable command can be run when the mpls ldp auto-config command has not been run in the IS-IS view, but the isis mpls ldp auto-config disable command does not take effect on interfaces.
If the isis mpls ldp auto-config disable command is run ahead of the mpls ldp auto-config command, the isis mpls ldp auto-config disable command can take effect on interfaces.
