BGP Community Catalog

This page lists all BGP communities supported by our network (AS 212895). Communities allow you to influence how your routes are handled — from traffic engineering and prepending to blackhole protection. Standard communities use the format ASN:Value, while Large Communities use ASN:Function:Parameter.

Location & Identity

Read-only identity tags: region, metro, datacenter and ingress router.

About BGP Communities
Standard Communities (RFC 1997)

Format: ASN:Value (16-bit:16-bit)

Used for well-known communities like No-Export (65535:65281) and blackhole routing (65535:666).

Large Communities (RFC 8092)

Format: ASN:Function:Parameter (32-bit:32-bit:32-bit)

Used for prepending, selective announcements, and advanced traffic engineering. The wildcard * means you provide the value (e.g. a target Peer ASN).
