 |2| Default routes (0/0) won't propagate inter-hub |0/0 routes won't propagate between two virtual WAN hubs. | June 2020 |  None. Note: While the Virtual WAN team has fixed the issue, wherein static routes defined in the static route section of the VNet peering page propagate to route tables listed in "propagate to route tables" or the labels listed in "propagate to route tables" on the VNet connection page, default routes (0/0) won't propagate inter-hub. |
 |3| Two ExpressRoute circuits in the same peering location connected to multiple hubs |If you have two ExpressRoute circuits in the same peering location, and both of these circuits are connected to multiple virtual hubs in the same Virtual WAN, then connectivity to your Azure resources might be impacted. | July 2023 | Make sure each virtual hub has at least 1 virtual network connected to it. This ensures connectivity to your Azure resources. The Virtual WAN team is also working on a fix for this issue. |
 |4| ExpressRoute ECMP Support | Today, ExpressRoute ECMP is not enabled by default for virtual hub deployments. When multiple ExpressRoute circuits are connected to a Virtual WAN hub, ECMP enables traffic from spoke virtual networks to on-premises over ExpressRoute to be distributed across all ExpressRoute circuits advertising the same on-premises routes. | | To enable ECMP for your Virtual WAN hub, please reach out to [email protected]. |
+| 5| Virtual WAN hub address prefixes are not advertised to other Virtual WAN hubs in the same Virtual WAN.| You can't leverage Virtual WAN hub-to-hub full mesh routing capabilities to provide connectivity between  NVA orchestration software deployed in a VNET or on-premises connected to a Virtual WAN hub to an Integrated NVA or SaaS solution deployed in a different Virtual WAN hub.  | | If your NVA or SaaS orchestrator is deployed on-premises, connect that on-premises site to all Virtual WAN hubs with NVAs or SaaS solutions deployed in them. If your orchestrator is in an Azure VNET, manage NVAs or SaaS solutions using public IP. Support for Azure VNET orchestrators is on the roadmap.|
