 ### Effective Routes
 
+> [!NOTE]
+> Getting the effective routes applied on Virtual WAN routing intent next hop resources is only supported for the next hop resource specified in private routing policies. If you are using both private and internet routing policy, check the effective routes on the next hop resource specified in the private routing policy for the effective routes Virtual WAN programs on the internet routing policy next hop resource. If you are using internet routing policies only, check the effective routes of the defaultRouteTable to view the routes programmed on the internet routing policy next hop resource.   
+  
 When private routing policies are configured on the Virtual Hub, all traffic between on-premises and Virtual Networks are inspected by Azure Firewall, Network Virtual Appliance, or SaaS solution in the Virtual hub.
 
 Therefore, the effective routes of the defaultRouteTable show the RFC1918 aggregate prefixes (10.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12) with next hop Azure Firewall or Network Virtual Appliance. This reflects that all traffic between Virtual Networks and branches is routed to  Azure Firewall, NVA or SaaS solution in the hub for inspection.

+### What is the maximum number of spoke Virtual Network addresses supported for hubs configured with Routing Intent?
 
+The maximum number of address spaces across all Virtual Networks directly connected to a single Virtual WAN hub is 400. This limit is applied individually to each Virtual WAN hub in a Virtual WAN deployment. Virtual Network address spaces connected to remote (other Virtual WAN hubs in the same Virtual WAN) hubs are not counted towards this limit.
+
+This limit is adjustable. For more information on the limit, the procedure to request a limit increase and sample scripts to determine the number of address spaces across Virtual Networks connected to a Virtual WAN hub, see [routing intent virtual network address space limits](../how-to-routing-policies#virtual-network-address-space-limits).
