This document describes a simple, interoperable mechanism that can be employed in IS-IS networks in order to decrease data loss associated with deterministic blackholing of packets during transient network conditions. The mechanism proposed here requires no IS-IS protocol changes and is completely interoperable with the existing IS-IS specification. The intention of this document is to provide an update to [RFC 3277].
