Abstract
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.
