Document Announcement Write-Up for
draft-ietf-opsec-blackhole-urpf currently in draft 04 having
completed WG last call and AD Evaluation.
Remote Triggered Black Hole (RTBH) filtering is a popular and
effective technique for the mitigation of denial-of-service
attacks. This document expands upon destination-based RTBH
filtering by outlining a method to enable filtering by source
address as well.
Working Group Summary
The WG last call period for draft-ietf-opsec-blackhole-urpf-03
was completed without opposition. Commentary on the draft
in the current and prior revision at IETF 74 and before would
indicate that the WG believes that the document is in suitable
form to advance. AD Review revealed insufficient warning on the
implications of using strict RPF. 04 revision is believed
to satisfy both AD concerns and WG participants.
As it documents existing current practice both in router
implementation and in operational practice and expands upon but
does not obsolete rfc 3882 we believe that it is suitable to
advance towards the goal of BCP status.
Review by both industry peers (NANOG security BOF), and one of
the originators of the method (Barry Greene) was solicited, and
their input is noted in the contributions section. Joel Jaeggli
Shepherded this document through the working group process. AD
review was provide by R. Bonica.
