# Configuring MPLS LSPs for VPWS

This section explains one way to create a basic MPLS configuration using the mpls and mpls ldp commands.

To configure MPLS LSPs on the PE router:

1. Enable MPLS on the virtual router.
   host1(config)#mpls
2. Configure the core-facing interface on which you want to enable MPLS, Label Distribution Protocol (LDP), and topology-driven LSPs.
   host1(config)#interface atm 5/0.100 host1(config-subif)#atm pvc 100 1 100 aal5snap 0 0 0 host1(config-subif)#ip address 192.168.5.5 255.255.255.0
3. Enable MPLS on the core-facing interface.
   host1(config-subif)#mpls
4. Enable LDP and topology-driven LSPs on the core-facing interface.
   host1(config-subif)#mpls ldp host1(config-subif)#exit
