The short version

BGP carries routing announcements between networks: a prefix, a path of autonomous systems, and attributes those networks use to choose.

What happened

BGP is a standing subject on the Networking desk. BGP carries routing announcements between networks: a prefix, a path of autonomous systems, and attributes those networks use to choose. The page keeps that sentence so a trend headline does not have to. A reader who arrived from a wire line can use the sources instead of the headline. BGP is named again here so the check is hard to miss: A reader separates the protocol that propagates the route from the system that validates the origin. The sources for BGP are listed below and are the place a quote should be verified.Futureweb.

The record

The record for BGP is RFC 4271. An announcement is not proof the announcer should have the prefix. That check is a separate system. Futureweb files the distinction here and leaves the source documents in the box, linked, rather than pasted. BGP is named again here so the check is hard to miss: A reader separates the protocol that propagates the route from the system that validates the origin. The sources for BGP are listed below and are the place a quote should be verified. A wire headline about BGP can be the reason a reader arrived. It is not the definition.

The document

The document to open for BGP is RFC 4271. BGP carries routing announcements between networks: a prefix, a path of autonomous systems, and attributes those networks use to choose. A second page that repeats a vendor adjective without this document has not added a fact.

Why it matters on this desk

What a reader can check

That check is a separate system. If the check cannot be done from the documents, the page is ahead of the record and should say so.

Where accounts differ

Accounts of BGP differ when one source states BGP carries routing announcements between networks: a prefix, a path of autonomous systems, and attributes those networks use to choose. and another skips the condition. An announcement is not proof the announcer should have the prefix. That check is a separate system. This page does not average those accounts into a third claim neither document made. BGP is named again here so the check is hard to miss: A reader separates the protocol that propagates the route from the system that validates the origin.

What to watch next

What would change this page

What is still specific

What stays specific to BGP is the pair of facts in the opening: BGP carries routing announcements between networks: a prefix, a path of autonomous systems, and attributes those networks use to choose. A reader separates the protocol that propagates the route from the system that validates the origin. Neighboring pages on the Networking desk answer a different question and should not be merged into this one.
