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.
Status of This Memo
This memo documents an Internet Best Current Practice.
This document is a product of the Internet Engineering Task Force

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].
