                   BGPsec Operational Considerations

Abstract

   Deployment of the BGPsec architecture and protocols has many
   operational considerations.  This document attempts to collect and
   present the most critical and universal.  Operational practices are
   expected to evolve as BGPsec is formalized and initially deployed.

1.  Introduction

   Origin validation based on the Resource Public Key Infrastructure
   (RPKI) [RFC6811] is in its early phases.  As BGPsec [RFC8205] may
   require larger memory and/or more modern CPUs, it expected to be
   deployed incrementally over a longer time span.  BGPsec is a new
   protocol with many operational considerations that this document
   attempts to describe.  As with most operational practices, they will
   likely change over time.

   BGPsec relies on widespread propagation of the RPKI [RFC6480].  How
   the RPKI is distributed and maintained globally and within an
   operator's infrastructure may be different for BGPsec than for origin
   validation.

   BGPsec needs to be spoken only by an Autonomous System's (AS's)
   eBGP-speaking border routers.  It is designed so that it can be used
   to protect announcements that are originated by resource-constrained
   edge routers.  This has special operational considerations, see
   Section 6.

   Different prefixes may have different timing and replay protection
   considerations.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

2.  Suggested Reading

   It is assumed that the reader understands BGP [RFC4271], BGPsec
   [RFC8205], the RPKI [RFC6480], the RPKI Repository Structure
   [RFC6481], and Route Origin Authorizations (ROAs) [RFC6482].
