Configuring Site-to-Site connectivity using VWAN

Another key design decision is how we are going to connect remote/on-premises networks to our VWAN hub. We can either do this via ExpressRoute or Site-to-Site VPN (S2S VPN) connections.

To implement S2S VPN connections, we need to deploy S2S VPN gateway instances into our VWAN hub by specifying the number of gateway scale units that we want. This can be done during the creation of the hub or added after. The number that we specify for Gateway scale units defines the aggregate maximum throughput that will be available for S2S VPN connections (Figure 7.25).

Figure 7.25 – VWAN hub gateway scale units

S2S VPN gateway instances in a VWAN hub are always deployed in an active-active setup (Figure 7.26). The maximum supported number of gateway scale units is 20 scale units (Figure 7.25), which deploys two active instances, with each instance supporting 10 Gbps (Figure 7.25). This requires an implementation...
