Abstract Abstract
This document describes a modification to the validation procedure This document describes a modification to the validation procedure
defined in RFC 5575 for the dissemination of BGP flow specifications. defined in RFC 5575 for the dissemination of BGP flow specifications.
RFC 5575 requires that the originator of the flow specification RFC 5575 requires that the originator of the flow specification
matches the originator of the best-match unicast route for the matches the originator of the best-match unicast route for the
destination prefix embedded in the flow specification. This allows destination prefix embedded in the flow specification. This allows
only BGP speakers within the data forwarding path (such as autonomous only BGP speakers within the data forwarding path (such as autonomous
system border routers) to originate BGP flow specifications. Though system border routers) to originate BGP flow specifications. Though
