If you enable STP for the CRF, you'll have a STP recalculation
(and loss of connectivity) every time there's a change in the CRF
state.

If you use the box for end-stations (as opposed to using it for
concentrators), that's going to make one hell of a difference for
the end-user experience...

If you select Spanning Tree in the top menu, you should be pre-
sented with a list of BRFs. I'm pretty sure you'll only see a
list of the preferred VLANs, so if you have no ports assigned
to the VLAN, you may not see them in that list. Try it out.
