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. This document describes four aspects
of the TRILL LAN Hello protocol used on such links, particularly
adjacency, designated RBridge selection, and MTU and pseudonode
procedures, with state machines. There is no change for IS-IS point-
to-point Hellos used on links configured as point-to-point in TRILL.
