a positive test proves Ze does what the requirement demands and a negative one proves it refuses what the requirement forbids
RFC 7611 - BGP ACCEPT_OWN Community Attribute
Every requirement this repository extracted from RFC 7611, the tests bound to it, and what a reader has verified about them. This summary is enrolled and gated by ./le rfc check.
Overview
Positive
what Ze has
the requirement admits no counter-case, so one polarity plus a recorded reason is the whole proof available for it
one direction is tested, the other is neither tested nor excused, and nothing states which
scoped tests exist; the remaining obligation is unmet or unproven, with zero whole-requirement credit
no test carries the requirement id, whether or not a gap states why
a red was observed once under a recorded procedure, and the unit, the claim and the producer it rested on still hash to what was recorded. The break is not re-run. A test pair is not a proof until one has been observed
Neutral
measures that are neither good news nor bad
MUST-level requirements the gate HOLDS. A population, not a result: the shares beside it are what says how Ze stands
an obligation that does not bind Ze. A {not-applicable} annotation says it never bound; a {feature-declined} annotation says its condition is an optional feature Ze does not offer, and quotes the RFC sentence that makes it optional. Scope, not coverage: it stays in the denominator every share on this page is taken over
a {not-applicable} annotation says the obligation does not bind Ze, so no test is owed for it. It stays in the denominator every share here is taken over
a {lower-layer} annotation says a layer under Ze performs the behavior, on state Ze installs into that layer, and names the producer that installs it. The obligation binds Ze and is met; Ze proves none of it, because its own boundary carries no value the behavior reads
a {feature-declined} annotation says the obligation is conditional on a feature the RFC makes optional and Ze does not offer, and it quotes the sentence that makes it optional. The condition is false, so nothing is owed and nothing is missing. It stays in the denominator every share here is taken over
The 8 shares marked as a part above are the whole of the 5 gated MUSTs: they add to 100%. Proven by a recorded break is a share of TAGGED UNITS, a different population, so it is not one of them.
How to read the colors
A color names what the measure MEANS, not how well Ze scores on it. Green is a good outcome at any value, red is a bad one, and neither a population nor a scope count is an outcome, so both take no color. The number under the label is what says how far Ze has got.
| Card | Tone here | Why that color |
|---|---|---|
| Gated MUSTs | neutral | no color: a population is a scale, and a larger one is neither good news nor bad. It is the accounting total |
| Out of scope | neutral | no color: an obligation that never bound Ze is neither an achievement nor a failure, and counting it either way would be a claim |
| Tested both ways | ok | green at every value: a test pair is the outcome this gate exists to produce, and the share under the label is what says how far Ze has got |
| One polarity plus reason | ok | green at every value: where no counter-case exists, one polarity IS the complete answer, and a recorded reason is what the gate demands beside it |
| One polarity, unexcused | ok | green at zero, RED above it: half a proof with no reason for the other half |
| Partial proof; remaining gap | ok | green at zero, RED above it: a tested clause cannot prove the whole requirement |
| No test at all | ok | green at zero, RED above it: a binding obligation nothing exercises is a claim with nothing behind it, whether or not a reason is stated |
| Not applicable | neutral | no color: an obligation that never bound Ze is neither an achievement nor a failure, and counting it either way would be a claim |
| Met below Ze | neutral | no color: an obligation met below Ze is neither a test Ze wrote nor work Ze owes, and the two green shares above are what says how much Ze proves itself |
| Optional feature declined | neutral | no color: an obligation whose condition Ze never meets is neither an achievement nor a failure. The absent FEATURE is disclosed on the RFC's own status row, as an implementation gap a later scope decision can revisit |
| Proven by a recorded break | ok | green at every value: an observed break is the outcome the discrimination gate exists to produce. The denominator is TAGGED UNITS, not obligations, so this share is not one of the parts above |
| Audit verdicts | warn | RED on the first weak, wrong or unimplemented verdict, amber while a verdict is no longer current or a gated MUST is unjudged, green when every one is judged sound and current |

Enrolment
Enrolled: Ze recognizes ACCEPT_OWN and implements the Section 2.2 discard for families without a Route Distinguisher. Optional re-import under Section 2.1 is disabled; normal loop checks remain active and the Section 3 VPN-IP decision step is not invoked. Conditional requirement scope follows that disabled mode, not an exemption from the non-RD receive rule.
What the public ledger says
No row in the public ledger, so its summary declares `| Support | - |` and docs/features/rfc-status.md carries no row for RFC 7611.
Coverage

| Positive and negative tests | 3 | one part of the gated population |
| Annotated (including scoped evidence) | 2 | one part of the gated population |
| One polarity only | 0 | one part of the gated population |
| No test and no annotation | 0 | one part of the gated population |
| Partial proof; remaining gap (subset of annotated; zero whole-requirement credit) | 0 | an overlay: each of these is also counted by the part it falls in |

RFC7611-5-1 | This approach may also be relevant in other scenarios where a BGP speaker maintains multiple routing contexts using an approach different from that of [RFC4364], as long as the specific approach in use has the property that the BGP speaker originates and receives routes within a particular context. In such a case, "VRF" in this document should be understood to mean whatever construct provides a routing context in the specific technology under consideration. Likewise, "Route Distinguisher" should be understood to mean whatever construct allows a route's originator to associate that route with its source context, and "Route Target" should be understood to mean whatever construct allows a route to be targeted for import into a context other than its source.

Proof state
A tagged unit reads unproven where no discrimination record exists for it: nothing in this tree has been observed to break it, so the claim its tag makes is unproven.
RFC7611-2.1-1
A route MUST NOT ever be accepted back into its source VRF, even if it carries one or more RTs that match that VRF (§2.1)
Audit verdict: not audited: no reader has judged these tests
| Polarity | Test | Kind and tier | Proof state |

unit/verify | revert, verified |

RFC7611-2.2-1
Likewise, if a route carrying the ACCEPT_OWN community is received in an address family that does not allow the source VRF to be looked up, the ACCEPT_OWN community MUST be discarded. (§2.2)
Audit verdict: enforced (the tests do what the requirement demands), fresh. Forbidden: keeping ACCEPT_OWN on a route in a family with no RD. TestACCEPTOwnFamilyBoundary covers IPv4 in the body NLRI; TestRFC7611AcceptOwnDiscardedForEveryNonRDFamilyInMPReach drives enforceRFC7606 with IPv6 unicast and IPv4 labeled unicast in MP_REACH_NLRI and asserts the COMMUNITY attribute shrinks to exactly 65001:100 (or disappears when ACCEPT_OWN was the only value) with MP_REACH byte-identical; negative VPN-IPv6 (RD present) keeps both copies. Red on a non-RD MP family keeping ACCEPT_OWN or an RD family losing it.

RFC7611-2.3-1
ACCEPT_OWN handling SHOULD be controlled by configuration, and if controlled by configuration, it MUST default to being disabled (§2.3)
Audit verdict: not audited: no reader has judged these tests
No test carries RFC7611-2.3-1, so no unit is bound to it.
RFC7611-2.3-2
When ACCEPT_OWN is disabled by configuration (either explicitly or by default), the router MUST NOT apply the special route acceptance rules detailed in Section 2.1. (§2.3)
Audit verdict: enforced (the tests do what the requirement demands), fresh. Forbidden: accepting, because it carries ACCEPT_OWN, a route whose ORIGINATOR_ID or NEXT_HOP is this router, while ACCEPT_OWN is disabled (ze has no ACCEPT_OWN config, so always). TestACCEPTOwnDoesNotEnableAcceptanceImplicitly asserts LoopIngress returns accepted == false for ORIGINATOR_ID == RouterID with ACCEPT_OWN attached (red on any ACCEPT_OWN exemption) and accepted == true for another originator. NEXT_HOP half: LoopIngress holds no own-NEXT_HOP refusal, so ACCEPT_OWN has no refusal to bypass there; the only acceptance the community could change is the ORIGINATOR_ID one the test asserts.
| Polarity | Test | Kind and tier | Proof state |

unit/verify | unproven |
| positive | TestACCEPTOwnDoesNotEnableAcceptanceImplicitly |

RFC7611-3-1
This extra step MUST only be invoked during the best path selection process of VPN-IP routes [RFC4364] (i.e., it MUST NOT be invoked for the best path selection of imported IP routes in a VRF). (§3)
Audit verdict: not audited: no reader has judged these tests
No test carries RFC7611-3-1, so no unit is bound to it.
