7.6. Interaction with Other Filtering Mechanisms in Routers

Implementations should provide mechanisms that map an arbitrary BGP community value (normal or extended) to Traffic Filtering Actions that require different mappings on different systems in the network. For instance, providing packets with a worse-than-best-effort per-hop behavior is a functionality that is likely to be implemented differently in different systems and for which no standard behavior is currently known. Rather than attempting to define it here, this can be accomplished by mapping a user-defined community value to platform-/network-specific behavior via user configuration.
