Duh!

Even though on the last couple of labs I've been able to get the TE tunnels up, I haven't been successful in actually routing traffic across them

During troubleshooting, I'd see the TE tunnel in the forwarding table, and verified mpls packets flowing through the tunnel. But the packets always seemed to get dropped at the endpoint. I thought this could have been something to do with the implicit-null issue, but forcing explicit nulls never helped.

I also noticed the mpls forwarding table showed no label for the TE tunnel. I thought maybe this was just a quirk of TE tunnels.

As it turns out, I need to enable mpls ip on the tunnel interface.
