VPNroutes

VPNroutes is a term used to describe the collection of routing information that governs how traffic traverses a virtual private network. It encompasses the routes learned or configured to reach remote networks through VPN tunnels, as well as the mechanisms used to install and update those routes on VPN gateways and end hosts. In practice, VPNroutes can refer to both the route tables on VPN devices and the dynamic routes exchanged by routing protocols across tunnels.

Two common models exist: route-based VPNs, which establish tunnel interfaces and install routes to remote networks, and policy-based VPNs, which select traffic by policies and may rely less on per-tunnel routes. Route-based VPNs typically rely on static or dynamic routing protocols such as BGP or OSPF to propagate VPNroutes between gateways, enabling automatic failover and scalable multi-site connectivity. In cloud environments, VPNroutes are often integrated into cloud VPC route tables, ensuring that remote networks are reachable via the VPN gateway.

Operation: when a VPN tunnel is up, the gateway learns or is configured with the remote networks, and the corresponding VPNroutes are installed in the local routing table. Dynamic routing allows automatic updates when networks change; static routes offer deterministic control. Common implementations use IPsec or WireGuard as the underlying tunnel, with tunnel endpoints exchanging route information.

Use cases: enterprise WAN connectivity, cloud interconnect, disaster recovery, and remote access. VPNroutes management involves monitoring route validity, avoiding route leakage, and ensuring correct segmentation and security policies. Split tunneling, NAT, and ACLs can affect how VPNroutes are applied.
