[rbridge] Configuration of VLANs vs selfconfiguration

Last I heard, there was nothing preventing the same MAC
address living in more than one VLAN. In fact, for routers and
VLAN bridges, wouldn't this be the dominant case?
If that has not changed, then the suggested approach will
not even work - independent of whether or not its in scope for
what we're trying to do.
While Harald's suggestion is interesting, IMO it would be part of an
rbridge only after it has been developed for bridges first.
This is not an rbridge issue.
