I wasn't particularily asking for suggestions, but for "I have this 
working, and this is how it looks like".  

This box is unlike any other Cisco "switch-like thing" I've had in my 
hands before, so it might very well be just not supported at all.

There isn't anything else you *can* configure (except changing the
global STP mode from pvstp to mst and back, and setup mst instances,
which does not have an effecit either).

So indeed, that's all there is, and the ASR920 MST/PVST+ documentation
claims "there is nothing else you can do".

*If* you have a vlan, you can do "spanning-tree vlan 10", but that is
default anyway (= not showing up in the config), but since there is no
"vlan 10" in the system, there's no spanning-tree instance for it either
("show vlans" comes up empty).
