Is EVPN expected to be forwarding BPDUs at all, intact or otherwise?
The way understand "how things are meant to be plugged together", you
should not see forwarded BPDUs - "containing layer2 madness to one
attachment site" is the whole point, isn't it?
I could see very special cases where it would be necessary, but that
would need to be a non-default-enabled switch.
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.
