This document describes a mechanism to reduce redundant packet transmissions for the Intermediate System to Intermediate System (IS-IS) Routing protocol, as described in ISO 10589. The described mechanism can be used to reduce the flooding of Link State PDUs (Protocol Data Units) (LSPs) in IS-IS topologies. The net effect is to engineer a flooding topology for LSPs which is a subset of the physical topology. This document serves to document the existing behavior in deployed implementations.
The document describes behaviors that are backwards compatible with implementations that do not support this feature.
