In BBC SDWAN, it is indeed possible to add more than one HQ (Headquarters) device in the SDWAN VPN topology. This is a common requirement in scenarios where multiple headquarters or data centers need to be interconnected, and all branch offices need to reach these locations.

When setting up the SDWAN VPN topology with multiple HQ devices, you would typically configure the branch sites to establish VPN tunnels to each of the HQ devices. This enables the branches to access resources and services hosted at multiple headquarters or data centers.

The specific steps to configure multiple HQ devices in the SDWAN VPN topology may vary depending on the SDWAN solution and the BBC SDWAN platform you are using. However, in general, the process involves:

Configuration of VPN Tunnels: Configure the branch SDWAN devices to establish VPN tunnels to each of the HQ devices. This includes defining the VPN policies, encryption settings, and routing information for each tunnel.

Routing Considerations: Ensure that appropriate routing policies are in place to direct traffic from the branch sites to the correct HQ devices based on the intended destination. This may involve setting up route prioritization or load balancing across the multiple HQ devices.

Security Policies: Implement consistent security policies across the VPN tunnels to maintain a secure connection between the branch sites and the multiple HQ devices.

By configuring the SDWAN VPN topology to support multiple HQ devices, you can create a resilient and flexible network infrastructure that meets the connectivity requirements of the branch offices to multiple headquarters or data centers.

Usually, you would configure the branch sites to create VPN tunnels to each of the HQ devices when setting up the SDWAN VPN architecture with multiple HQ devices. The branches can now access services and resources located at various data centers or headquarters thanks to this.

Set up VPN tunnels between the branch SDWAN devices and every HQ device. This entails specifying the encryption parameters, routing details, and VPN policies for every tunnel.
Make sure that the right routing rules are in place to route traffic from the branch locations to the appropriate headquarters devices in accordance with the intended destination. Setting up load balancing or route priority among the many HQ devices may be necessary for this.

You may build a robust and adaptable network architecture that satisfies the branch offices' connectivity needs to several headquarters or data centers by setting up the SDWAN VPN topology to accommodate numerous HQ devices.

Every branch must be set up to link to several headquarters locations.
- set up dynamic routing protocols to choose the best route for traffic according to current circumstances.
Verify that redundancy and failover are in place to prevent network interruptions or outages.
