5) Introduction - Bridging limitation. The first paragraph refers to
Ethernet networks used without Spanning Tree. This is irrelevant, since
Spanning Tree is always deployed in conjunction with Ethernet. The
correct contrast must be between Ethernet with Spanning Tree and
Ethernet with TRILL. The claim of a single broadcast/flooding domain is
incorrect since VLANs have solved this issue many years ago.
"always" is too strong, since most unmanaged bridges (intended for
consumers' home networks, but often dangled off the edge of corporate
networks as port expanders, without asking for permission) don't seem to be
supporting Spanning Tree. However, these are not going to support TRILL
either, so for the environments considered here, "always" is probably true.
