The TRILL (Transparent Interconnection of Lots of Links) protocol [RFC6325] provides least-cost pair-wise data forwarding without configuration in multi-hop networks with arbitrary topologies and link technologies, safe forwarding even during periods of temporary loops, and support for multipathing of both unicast and multicast traffic. TRILL accomplishes this with the IS-IS (Intermediate System to Intermediate System) [IS-IS] [RFC1195] [RFC7176] link-state routing protocol using a header with a hop count. The design supports optimization of the distribution of multi-destination frames and two types of data labeling: VLANs (Virtual Local Area Networks) [RFC6325] and FGLs (fine-grained labels) [RFC7172]. Devices that implement TRILL are called TRILL switches or RBridges (Routing Bridges).

Transparent Interconnection of Lots of Links (TRILL): End Station Address Distribution Information (ESADI) Protocol
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 topologies and link technologies. TRILL supports multipathing of both unicast and multicast traffic. Devices that implement the TRILL protocol are called TRILL switches or RBridges (Routing Bridges).
ESADI (End Station Address Distribution Information) is an optional protocol by which a TRILL switch can communicate, in a Data Label (VLAN or fine-grained label) scoped way, end station address and reachability information to TRILL switches participating in ESADI for the relevant Data Label. This document updates RFC 6325, specifically the documentation of the ESADI protocol, and is not backwards compatible.
