The IETF TRILL (TRansparent Interconnection of Lots of Links)
protocol provides least cost pair-wise data forwarding without
configuration in multi-hop networks with arbitrary topology, 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 (Intermediate System to Intermediate
System) 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 (Local Area Network) 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 (Virtual LAN) be handled by at most one RBridge. The purpose of
this document is to improve the documentation of the Appointed
Forwarder mechanism.
