The IETF TRILL protocol provides optimal pair-wise data forwarding
without configuration, safe forwarding even during periods of
temporary loops, and support for multipathing of both unicast and
multicast traffic. TRILL accomplishes this by using IS-IS link state
routing and by encapsulating traffic using a header that includes a
hop count. Devices that implement TRILL are called RBridges.

TRILL supports multi-access LAN links that can have multiple end
stations and RBridges attached. Where multiple RBridges are attached
to a link, native traffic to and from end stations on that link is
handled by a subset of those RBridges called Appointed Forwarders,
with the intent that native traffic in each VLAN be handled by at
most one RBridge.  The purpose of this document is to improve the
documentation of the Appointed Forwarder mechanism.
