Faster convergence is a critical feature of Transparent Interconnection of Lots of Links (TRILL) [RFC6325] networks. The TRILL IS-IS Hellos [RFC7177] [IS-IS] used between RBridges provide a basic neighbor and continuity check for TRILL links. However, failure detection by non-receipt of such Hellos is based on the Holding Time parameter that is commonly set to a value of tens of seconds and, in any case, has a minimum expressible value of one second.

Transparent Interconnection of Lots of Links (TRILL): Bidirectional Forwarding Detection (BFD) Support
This document specifies use of the Bidirectional Forwarding Detection (BFD) protocol in Routing Bridge (RBridge) campuses based on the RBridge Channel extension to the Transparent Interconnection of Lots of Links (TRILL) protocol.
BFD is a widely deployed Operations, Administration, and Maintenance (OAM) mechanism in IP and MPLS networks, using UDP and Associated Channel Header (ACH) encapsulation respectively. This document specifies the BFD encapsulation over TRILL.
