Transparent Interconnection of Lots of Links (TRILL):
End Station Address Distribution Information (ESADI) Protocol
Abstract
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.
