BGP communities are a method to group a set of prefixes and apply some attributes, such as local preference, or route filtering, to all the members of that group. This grouping is done through assigning a "community" value to an IP prefix.

For example, a network administrator can create a community with the value 65000:100 and assign it to all the prefixes that belong to a specific customer. The routers in the network can then be configured to give a higher local preference to all prefixes that have that community value, ensuring that traffic for that customer will always be preferred over other customers.

A common use of BGP communities is to control the distribution of routes between different ASNs. For example, a network operator may use communities to ensure that only certain prefixes are exported to specific customers or peers.
