Thanks Adam, but I was only talking about the RSVP-TE signaled bandwidth
reservation (not the actual qos, which I think is what you are referring to)
.... a guy on NANOG mail list answered it for me.  This is what I was
missing on the Headend TE-Tunnel interface config... 

interface tunnel-te1
signalled-bandwidth 5000


...that one simple command.  Now all LSR's in the RSVP-TE path allocate that
bandwidth...

Seen with these commands...
