BGP communities

BGP communities are labels added to internet routing information that help network administrators manage and control how data travels across the internet. Think of them as categories or tags attached to data routes, allowing easier organization, filtering, or routing decisions based on policies. For example, a provider can assign a community tag to direct certain data to specific destinations or prioritize certain traffic. These tags are flexible and support complex routing strategies, making the management of large, interconnected networks more efficient and precise while maintaining the stability and performance of internet communications.
