 Dynamic routing allows routers to automatically exchange reachability information using protocols such as BGP, rather than requiring an administrator to manually configure every individual route.

+A high availability (HA) setup is an infrastructure without a single point of failure. It prevents a server failure by adding redundancy to every layer of your architecture.

 ## IPsec
 
 **I**nternet **P**rotocol **Sec**urity (IPsec) is a suite of protocols used to secure IP communications by authenticating and encrypting each IP packet in a data stream. In the context of Scaleway Site-to-Site VPN, IPsec provides end-to-end security for traffic flowing through the VPN tunnel between a VPN gateway and a customer gateway.

 Site-to-Site VPN connections are secured with Internet Protocol security (IPsec). When creating a VPN [connection](/site-to-site-vpn/reference-content/understanding-s2svpn/#connection), you are prompted to define a **security proposal** (aka IPSec proposal) which defines the precise encryption and authentication methods to secure the tunnel. Read more about security proposals and encryption in our [dedicated documentation](/site-to-site-vpn/reference-content/security-proposals/).
 
+### Does Site-to-Site VPN offer high availability (HA) or multi-site capabilities?
+
+Yes, you can easily set up a high availability and/or multi-site deployment by creating VPN gateways in different Availability Zones of a Region for a given Private Network.

+Refer to the [dedicated documentation](/site-to-site-vpn/reference-content/ha-multisite-configurations) for reference HA/multi-site configurations.

+Site-to-site VPN allows you to set up high availability and multi-site deployments by creating VPN gateways in different Availability Zones of a Region for a given Private Network. 
+
+Adding redundancy with a second VPN gateway eliminates single points of failure for critical infrastructure. You can then connect several discrete infrastructures to set up large-scale multi-site deployments.
