BGPsec Validation State Unverified
draft-borchert-sidrops-bgpsec-state-unverified-04
Abstract
In case operators decide to delay BGPsec path validation, none of the
available states do properly represent this decision. This document
introduces "Unverified" as a well-defined validation state which
allows to properly identify a non-evaluated BGPsec routes as not
verified.

Internet Draft BGPsec Validation State Unverified January 15, 2021
1. Introduction
BGPsec path validation [RFC8205] provides well defined validation
states. Though, there are instances in which BGPsec routes are not
immediately validated upon receiving them. This could be due to
configuration where the operator chose to perform "Lazy Evaluation"
or due to instances where router configuration could enable the
operator to delay route validation during situations of unexpectedly
high loads such as DDOS attacks or others. Here, the absence of a
well-defined initialization state requires to use a validation state,
that is otherwise well-defined and therefore "waters" down the
meaning of that state.
Hence, this document updates the RFC 8205 by adding the proposed
validation state "Unverified".
1.1. Terminology
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] and BGPsec
Protocol Specification [RFC8205]
