Your company deploys Azure Route Server in a hub VNet to exchange routes with a third-party SD-WAN NVA. Several spoke VNets are peered to the hub. Workloads in the spokes must automatically learn the on-premises branch routes that the NVA advertises to Route Server, without configuring user-defined routes in each spoke. When you configure the VNet peering between the hub and each spoke, which setting must you enable on the peering so the spokes receive the branch routes learned by Route Server?
