If RBridges are casually assigned as Appointed Forwarders for VLANs
without considering the number of MAC addresses and traffic load of
these VLANs, it may overload some of the RBridges while leave other
RBridges lightly loaded, which reduces the scalability of a RBridge
network and undermines its performance.
There can only be a single appointed forwarder for one VLAN carried
by a LAN link at the same time, even if this LAN link is attached to
multiple points of an RBridge campus. This limitation not only wastes
the available access bandwidth of RBridge campus but also reduces its
reliability.
A new protocol is designed in this document to support the adaptive
VLAN assignment (or Appointed Forwarder selection) based on the
forwarders' reporting of their usage of MAC tables and available
bandwidth. Link aggregation is proposed to overcome the single
forwarder limitation of TRILL.
