The IETF TRILL (Transparent Interconnection of Lots of Links) [RFC6325] protocol provides loop-free and per-hop-based multipath data forwarding with minimum configuration. TRILL uses IS-IS [IS-IS] [RFC6165] [RFC7176] as its control-plane routing protocol and defines a TRILL-specific header for user data. In a TRILL campus, communications between TRILL switches can:

Problem Statement and Goals for Active-Active Connection at the Transparent Interconnection of Lots of Links (TRILL) Edge
The IETF TRILL (Transparent Interconnection of Lots of Links) protocol provides support for flow-level multipathing with rapid failover for both unicast and multi-destination traffic in networks with arbitrary topology. Active-active connection at the TRILL edge is the extension of these characteristics to end stations that are multiply connected to a TRILL campus. This informational document discusses the high-level problems and goals when providing active- active connection at the TRILL edge.
