The IETF TRILL (Transparent Interconnection of Lots of Links) protocol [RFC6325] provides optimal pair-wise data frame 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 [IS-IS] [RFC7176] link-state routing and encapsulating traffic using a header that includes a Hop Count. Devices that implement TRILL are called RBridges (Routing Bridges) or TRILL switches.

Transparent Interconnection of Lots of Links (TRILL): Pseudo-Nickname for Active-Active Access
The IETF TRILL (Transparent Interconnection of Lots of Links) protocol provides support for flow-level multipathing for both unicast and multi-destination traffic in networks with arbitrary topology. Active-active access at the TRILL edge is the extension of these characteristics to end stations that are multiply connected to a TRILL campus as discussed in RFC 7379. In this document, the edge RBridge (Routing Bridge, or TRILL switch) group providing active- active access to such an end station is represented as a virtual RBridge. Based on the concept of the virtual RBridge, along with its pseudo-nickname, this document specifies a method for TRILL active- active access by such end stations.
