How it works...

We use the same methodology as used to configure the interfaces and OSPF, by using a Jinja2 template to generate the needed MPLS configuration for the Juniper devices in our inventory, and the following is a sample of the MPLS configuration for the mxpe02 router:

protocols {
    ldp {
        interface ge-0/0/0.0;
        interface ge-0/0/1.0;
        interface lo0.0;
    }
    rsvp {
        interface ge-0/0/0.0;
        interface ge-0/0/1.0;
    }
    mpls {
        interface ge-0/0/0.0;
        interface ge-0/0/1.0;
    }
}
