BGPsec Validation State Signaling
draft-sidrops-bgpsec-validation-signaling-05
Abstract
This document defines a new BGP non-transitive extended community to
carry the BGPsec path validation state. BGP speakers that receive
this community string can use the embedded BGPsec validation state in
conjunction with configured local policies to influence their
decision process. The ability to accept and act on BGPsec path
validation state from a neighbor allows for a reduction of path
validation processing load and/or increased resilience in the event
that a router is temporarily unable to perform local path validation.

1. Introduction
This document defines a new BGP non-transitive extended community to
carry the BGPsec path validation state. BGP speakers that receive
this community string can use the embedded BGPsec validation state in
conjunction with configured local policies to influence their
decision process. The ability to accept and act on BGPsec path
validation state from a neighbor allows for a reduction of path
validation processing load and/or increased resilience in the event
that a router is temporarily unable to perform local path validation.
