| Community | Name |
|---|---|
62484:0 | Any: Any route that has traversed AS62484 |
62484:64810:x | Route Server ID: x is equal to the Route Server ID on which the route was received |

Community Filtering
To mitigate community "noise", all BGP communities not specified in this document are deleted from inbound BGP updates, and only communities in the Informational Communities section are exported.
The only exception to this are Well Known Communities — all supported well-known BGP communities are maintained on outbound updates.
