I have created a tunnel-te from xrv16 to csr3, the tunnel is up and getting Pop label to csr3 that's ok.
From xrv16 I have learned the route to xrv17 over the tunnel, but checking the Label it's unlabbled as well.
I believe the route from xrv16 to xrv17 would be labeled normally over the tunnel-te or am I wrong?
Base topology.
