 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.
 
+## High availability
+
+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 letting you deploy VPN gateways across multiple Availability Zones within a Region, all attached to the same Private Network.
+
+Adding redundancy with a second VPN gateway eliminates single points of failure for critical infrastructure. You can then connect several distinct infrastructures to set up large-scale multi-site deployments.
+
+## Single site configuration without redundancy
+
+ In this configuration, a VPN gateway in a single Availability Zone connects to a customer gateway in a single remote infrastructure.

+
+## Single site configuration with redundancy on Scaleway side
+
+The schema below represents a Site-to-Site VPN configuration between two VPN gateways in two AZs, attached to a single Private Network in a single VPC on the Scaleway side, and connected to a customer gateway in a single remote infrastructure. This setup offers high availability on the Scaleway side.

+## Single site configuration with crossed redundancy on both Scaleway and customer sides
+
+The schema below represents a Site-to-Site VPN configuration between two VPN gateways in two AZs, attached to a single Private Network in a single VPC on the Scaleway side, each connected to two customer gateways in a single remote infrastructure. This setup offers high availability on both the Scaleway and customer sides, with crossed redundancy for the connections.

+
+## Multi-site configuration with crossed redundancy on both sides
+
+The schema below represents a Site-to-Site VPN configuration between two VPN gateways in two AZs, attached to a single Private Network in a single VPC on the Scaleway side, each connected to four customer gateways across two remote infrastructures. This setup offers high availability on the Scaleway side, and each site on the customer side, with crossed redundancy for the connections.
