Technical Summary
This specification provides for any Explicit Congestion Notification
(ECN) marking in traffic ingressed by TRILL to be copied into the
TRILL Extension Header Flags Word [RFC7179]. It also enables
congestion marking by a congested transit TRILL switch in the TRILL
Header Extension Flags Word. At TRILL egress, it specifies how any
ECN markings in the TRILL Header Flags Word and in the encapsulated
traffic are combined so that subsequent forwarding elements can see if
congestion was experienced at any previous point in the path from the
Source.
