Turn-up rules
Predictable behavior during incidents.
Community handling is deterministic. Source tags describe where routes were learned, while 9990-9993 communities control export and prepending toward the target ASN.
Communities are evaluated only on accepted customer routes after prefix ownership, IRR, and RPKI checks pass.
215828:0:* communities are informational source tags for routes learned by AS215828.
215828:9991, 9992, and 9993 prepend one, two, or three times toward the target ASN.
215828:9990 suppresses export toward the target ASN listed in the third community field.
Examples
How customers use the communities.
De-prefer Arelion
Route
203.0.113.0/24Communities
215828:9992:1299AS215828 prepends twice when announcing the route toward Arelion AS1299.
Suppress Hurricane export
Route
198.51.100.0/24Communities
215828:9990:6939The route is not exported toward Hurricane Electric AS6939.
Customer source tag
Route
192.0.2.0/24Communities
215828:0:4The route is marked as learned from CONE / Customer in the AS215828 community set.
Target ASN
The third field is the target ASN, for example 1299, 6939, 51202, 47498, or 62255.
Prepend levels
Use 9991, 9992, or 9993 to prepend once, twice, or three times toward the target ASN.
No export
Use 9990 with the target ASN to suppress export toward that specific network.
Learned-from tags
215828:0:1 through 215828:0:4 describe whether a route was learned from transit, IXP RS, peering, or customer cone.
Production note
These entries are taken from the BGP.tools AS215828 communities view. Confirm production routing changes with NOC before applying export-suppression or heavy prepending on live prefixes.
Need a custom export policy?
TMW can add or document additional per-upstream, per-IX, or per-region communities during customer turn-up when the routing policy is defined in the order or NOC ticket.
