# How to configure virtual hub routing
1515

16-
A virtual hub can contain multiple gateways such as a Site-to-site VPN gateway, ExpressRoute gateway, Point-to-site gateway, and Azure Firewall. The routing capabilities in the virtual hub are provided by a router that manages all routing, including transit routing, between the gateways using Border Gateway Protocol (BGP). This router also provides transit connectivity between virtual networks that connect to a virtual hub and can support up to an aggregate throughput of 50 Gbps. These routing capabilities apply to Standard Virtual WAN customers.

* **Resource group**: Select the resource group that contains the virtual network to which you want to connect.

* **Virtual network**: Select the virtual network you want to connect to this hub. The virtual network you select can't have an already existing virtual network gateway.
2721
* **Propagate to none**: This is set to **No** by default. Changing the switch to **Yes** makes the configuration options for **Propagate to Route Tables** and **Propagate to labels** unavailable for configuration.

* **Associate Route Table**: From the dropdown, you can select a route table that you want to associate.
23+
* **Propagate to labels**: Labels are a logical group of route tables. For this setting, select from the dropdown.

* **Static routes**: Configure static routes, if necessary. Configure static routes for Network Virtual Appliances (if applicable). Virtual WAN supports a single next hop IP for static route in a virtual network connection. For example, if you have a separate virtual appliance for ingress and egress traffic flows, it would be best to have the virtual appliances in separate VNets and attach the VNets to the virtual hub.

* **Bypass Next Hop IP for workloads within this VNet**: This setting lets you deploy NVAs and other workloads into the same VNet without forcing all the traffic through the NVA. This setting can only be configured when you're configuring a new connection. If you want to use this setting for a connection you've already created, delete the connection, then add a new connection.
