This memo provides a method for protecting a router's control plane
from undesired or malicious traffic. In this approach, all
legitimate router control plane traffic is identified. Once
legitimate traffic has been identified, a filter is deployed in the
router's forwarding plane. That filter prevents traffic not
specifically identified as legitimate from reaching the router's
control plane, or rate-limits such traffic to an acceptable level.
Note that the filters described in this memo are applied only to
traffic that is destined for the router, and not to all traffic that
is passing through the router. This document is not an Internet
Standards Track specification; it is published for informational
purposes.
This document is a product of the Operational Security Capabilities for IP Network Infrastructure Working Group of the IETF.
