Azure ExpressRoute and VPN Gateway Now Support Summarized Route Advertisement
Azure ExpressRoute and VPN Gateway now generally support summarized advertised gateway prefixes, allowing aggregated prefixes to be advertised to on-premises networks. This capability helps large hub-and-spoke deployments avoid exceeding advertised-prefix limits, eliminating the need to re-architect address plans or split virtual networks. The feature supports both IPv4 and IPv6 address spaces and ensures existing connectivity is preserved for address spaces outside summarized prefixes.

- Support for Summarized Advertised Gateway Prefixes
Azure ExpressRoute and VPN Gateway now allow specifying aggregated (summarized) prefixes for advertising to on-premises networks, replacing individual virtual network address spaces. This enhancement helps large hub-and-spoke deployments manage route counts effectively, preventing advertised-prefix limits from being reached as spokes are added.
