Upstream Provider Authorization for Research and Education Networks

Development of this web tool was supported in part by the National Science Foundation (OAC-2530871).

Not every provider is visible in public BGP data. This tool builds its recommendations from AS paths observed by public route collectors. Relationships that do not normally appear in the global routing table — most commonly backup providers, failover-only links, and paths suppressed by local-preference or upstream filtering — will be absent from the list below.

Under the ASPA verification procedure, any upstream not listed in your ASPA is treated as Invalid, so publishing an ASPA built only from currently-observed paths can cause your backup routes to be rejected at the moment they are needed. Reconcile the suggestions with your own provider contracts and failover policy before registering an ASPA object.
