The spec currently says (in section 126.96.36.199 Transmission of BPDUs)
RBridges MAY support a capability for sending spanning tree BPDUs for
the purpose of attempting to force a bridged LAN to partition as
discussed in Section A.3.3. Except for this optional capability,
RBridges MUST NOT send spanning tree BPDUs.
I don't remember any discussion on saying that RBridges MUST NOT send
BPDUs. I remember
at one point requiring it, and saying that an RBridge is DRB if and only
if it is the Spanning tree Root.
(I still would prefer that, by the way -- makes all the controversial
per VLAN Hellos
I remember it being removed from the spec (because of complexity with n
spanning tree, and links with no bridges, perhaps, where the spanning
tree messages would
be unnecessary overhead), but I don't remember any reason to say
RBridges MUST NOT sent
Anyone else remember?
