RPKI and Route Origin Validation Explained

Check route origin validation for a prefix you originate, and do not advertise anyone else's network.

Updated 25 October 2026 · Explainer

This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.

What this hour is for

RPKI lets a holder publish which autonomous system may originate a prefix. A validator compares a route you are looking at with that authorization. You check prefixes you originate, or a route you received and are allowed to reason about. You do not create an authorization for a prefix you do not hold.

An invalid origin is a route you do not prefer. Dropping it is a routing policy on your own edge, written down. It is not a tool for blackholing a network you dislike.

The IRR object is a different database with a similar question. Write which one you used. A lab prefix must not be advertised to the internet.

BGP on this page does not open a session to a stranger.

The change you can finish

Apply nothing during the writing of the note. When the lab window opens, it is one change on the device named in the ticket. Read the draft, then the device, then decide.

Rollback is the file or the revision you saved first. You do not invent a rollback after the only copy is gone.

  1. Name a prefix you originate.
  2. Read the validation state.
  3. Write valid, invalid, or not found.
  4. Do not authorize a prefix you do not hold.
  5. Do not advertise a lab prefix.
  6. Stop.

Mistakes that outlive the command

RPKI and Route Origin Validation Explained goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.

Decisions to write down

One decision for RPKI and Route Origin Validation Explained: The prefix is yours to originate. The state is written. No foreign ROA was created. No lab prefix was advertised. And no new BGP session was opened.

Checks before you call it done

Confirm this before you call the change done: One prefix was checked. The state is in the ticket. The origin ASN matches your authority. Nothing was advertised as a test. And the session list is unchanged. If one of those fails, stop.

Before you leave the device

RPKI and Route Origin Validation Explained ends when the hostname on the device matches the hostname in the ticket. If it does not, you are on the wrong box. Stop. A command that succeeded on the wrong box is not progress.

The draft stays a draft until a person has read the names in it. A generator does not log into the device and does not know which interface is the uplink. You delete a line that names a device, a zone, or a prefix you did not write down.

0.0.0.0/0 is not kept because a sample included it. A source you can say is the source you keep. 192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. They belong in the note. They are not prefixes you type onto a production device because they appeared in a draft.

prompt-for-this is a reminder that a secret is missing. It is not a password, a key, a community string, or a pre-shared key you save in the ticket or in git. The real secret stays in the store.

One change is the window. A VLAN and a routing protocol and a VPN do not share it. If two things move and the result is wrong, you will not know which one did it. The next feature waits for its own page.

If the same step fails twice, stop for the day. The failure is the result. Adding a forum command beside a half-applied config produces a device nobody can rebuild. Restore the copy you took first.

A second person reads the device name and the change aloud. If they cannot find them in the ticket, the note is not done. Silence is not agreement. Then leave the device alone.

This page is a planning guide. It is not a vendor manual, not an official standard, and not a permission to touch a network you do not administer. The pillar guide owns the wider design. This page owns one lab proof.
