On the subinterfaces

I started with 5000 and 2000 on the tunnel but after the recommendation to
lower it, I tried lowering it but didnt help.

Here is the sh mpls traff topo

Subject: Re: MPLS Traffic-Engineering Dynamic Tunnel

"No path to destination" can be misleading because it does not really mean
there is no route. It just means it cannot calculate a path that meets the
requirements of the tunnel. I am curious to see the full configs as well as
"show mpls traffic-eng topology."

R8 does not have route to loopback of R9, and R9 does not have route to

loopback of R8. Enable ISIS on loopbacks by "ip router isis" or change your

TE router-ID to reachable ones.
