+The default BGP route priority is `100`. This base priority can be adjusted using communities. For example, when a route is tagged with the community `13335:60010` its priority is set to `10`. This makes it a higher priority than the default of `100` because lower numeric values are preferred. This operates similarly to local preference communities. However, unlike local preference, these combine numerically with AS prepends. This means that for each AS prepending — where the customer ASN is added multiple times to the AS Path — an additional `10` is added to the route's base priority. By increasing the priority number, the route is less preferred.
