General availability: ExpressRoute private peering support for BGP communities
Published date: 12 July, 2023
ExpressRoute private peering now supports the use of custom Border Gateway Protocol (BGP) communities with virtual networks connected to your ExpressRoute circuits. Once you configure a custom BGP community for your virtual network, you can view the regional and custom community values on outbound traffic sent over ExpressRoute when originating from that virtual network. These values can be used when applying filters or specifying routing preferences for traffic sent to your on-premises from your Azure environment.
