Enabling Global MPLS LDP

You can perform other MPLS LDP configurations only after enabling global MPLS LDP.

Perform the following steps on each node in an MPLS domain.

Access the system view.
```
system-view
```
Enable MPLS LDP globally and access the MPLS LDP view.
```
mpls ldp
```
By default, LDP is not enabled globally.
(Optional) Set the LSR ID for an LDP instance.
lsr-id lsr-id

By default, the LSR ID of the LDP instance is the LSR ID of the local node. It is recommended that the default value be used.

In certain networking where VPN instances are used, such as BGP/MPLS IP VPN networking, if the VPN address and the LSR ID overlap, you need to configure LSR IDs for LDP instances to ensure that TCP connections can be correctly set up.
