Right, I'd only expect this to work in very specific "make it entirely 
transparent" cases...  It looks like both Cisco and Huawei document 
options related to BPDU tunneling, and neither enable any of it by 
default.  Not coming up with much else for comparison.

Juniper is now telling me that this is occuring by design, but can't point 
to any documentation or standards which support that, nor explain why it 
suddenly changed post-upgrade.  I'm... not convinced.
