RE: MX204 tunnel services BW

[Jeff Behrns via NANOG]

JTAC says we must disable a physical port to allocate BW for tunnel-services.  
Also leaving tunnel-services bandwidth unspecified is not possible on the 204.  
I haven't independently tested / validated in lab yet, but this is what they 
have told me.  I advised JTAC to update the MX204 "port-checker" tool with a 
tunnel-services knob to make this caveat more apparent.
