+### Use more user-defined routes in a single route table
+
+In Azure Virtual Network Manager UDR management, users can now create up to 1,000 user-defined routes (UDRs) in a single route table, compared to the traditional 400-route limit. This higher limit enables more complex routing configurations, such as directing traffic from on-premises data centers through a firewall to each spoke virtual network in a hub-and-spoke topology. This expanded capacity is especially useful for managing traffic inspection and security across large-scale network architectures with numerous spokes.

 When you add other virtual networks to a network group, the routing configuration is automatically applied to the new virtual network. Your network manager automatically detects the new virtual network and applies the routing configuration to it. When you remove a virtual network from the network group, the applied routing configuration is automatically removed as well.

+The following are impacts of UDR management with Azure Virtual Network Manager on routes and route tables:
 
 - When conflicting routing rules exist (rules with same destination but different next hops), they aren't supported within or across rule collections that target the same virtual network or subnet.
 - When you create a route rule with the same destination as an existing route in the route table, the routing rule is ignored.
 - When a virtual network manager-created UDR is manually modified in the route table, the route isn't up when an empty commit is performed. Also, any update to the rule isn't reflected in the route with the same destination.
 - Existing Azure services in the Hub virtual network maintain their existing limitations with respect to Route Table and UDRs.
 - Azure Virtual Network Manager requires a managed resource group to store the route table. If you need to delete the resource group, deletion must happen before any new deployments are attempted for resources in the same subscription.
-- UDR Management supports creating 1000 UDRs within a route table. This means that you can create a routing configuration with a maximum of 1,000 routing rules. 
+- UDR management allows users to create up to 1000 UDRs per route table.
