Don't use a virtual-switch, just use a regular vpls instance, and add
a routing-interface irb.1111.  Addionally use connectivity-type irb so
the VPLS instance stays up even with no physical ports in it:

TEST {
    instance-type vpls;
    route-distinguisher 1.2.3.5:1111;
    vrf-target target:1111:1111;
    routing-interface irb.1111;
    protocols {
        vpls {
            site-range 3;
            no-tunnel-services;
            site B {
                site-identifier 1;
            }
	    connectivity-type irb;
        }
    }
}
