Yes, Sangfor BBC SDWAN allows you to add more than one HQ device in the SDWAN VPN topology. This can be useful for a variety of reasons, such as:
Load balancing: Distributing traffic across multiple HQ devices can improve performance and availability for your branches.
Redundancy: If one HQ device goes down, the others can take over and keep your branches connected.
Geographic diversity: You can place HQ devices in different locations to improve latency and resiliency for branches in those regions.
There are two main ways to add more than one HQ device to your Sangfor BBC SDWAN topology:
Full mesh: In this configuration, each branch device has a VPN tunnel to every HQ device. This provides the best possible redundancy and load balancing, but it can also be the most complex and expensive to set up.
Hub-and-spoke: In this configuration, all branch devices tunnel to a central hub device, which then tunnels to each of the HQ devices. This is a simpler and more cost-effective way to add redundancy, but it can create a single point of failure if the hub device goes down.
The best way to configure your Sangfor BBC SDWAN topology will depend on your specific needs and requirements. If you're not sure which option is right for you, I recommend talking to a Sangfor sales engineer.
Here are some additional things to keep in mind when adding more than one HQ device to your Sangfor BBC SDWAN topology:
You will need to have enough VPN licenses to cover all of your devices.
You will need to configure the routing and security policies for your HQ devices.
You may need to upgrade your hardware or software to support the additional devices.
