How to configure IGP-based LDP Automatic Configuration

At first we should to know what is the IGP-based LDP Automatic ?

IGP-based LDP automatic configuration reduces configuration workloads and ensures correct configurations.

To configure IGP-based MPLS LDP, you need to enable MPLS LDP globally first and then on the interfaces that need the function. If a large number of interfaces need MPLS LDP, you need to configure them one by one, which is time-consuming and prone to configuration incorrectness.

To address this issue, configure IGP-based LDP automatic configuration. With IGP-based LDP automatic configuration, MPLS LDP is enabled automatically on IGP-capable interfaces after MPLS LDP is enabled globally.

If you have deploy the IS-IS as the IGP, you can configure the LDP automatic configuration is as below:

#

isis 1

mpls ldp   auto-config

#

commit

#

Note:

After the command is run, 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.
