D Configuring a Gateway-to-Gateway VPN Tunnel Between RV0xx Series Routers This appendix explains how to set up a VPN between two RV0xx Series routers. You can then repeat the procedures to add tunnels to your other sites. A Cisco RV0xx Series router supports up to 100 VPN tunnels. NOTE Even if you have an RV0xx Series router on one end of the tunnel, and a different model on the other end, you can use this information to set up your RV0xx Series router. Note the shared settings that you need to configure on your other router. Both devices must use a common key or certificate and must have the same security policies set up. Refer to these topics: Overview, page 1 Topology Options, page 170 Other Design Considerations, page 173 Configuring a VPN Tunnel on a Cisco RV0xx Series Router, page 175 Topology Options Before you configure the VPN settings on your routers, consider the topology options. A VPN topology specifies the peers and the networks that are part of the VPN and how they connect to one another. Depending on the number of sites and the nature of traffic, you can choose a hub-and-spoke topology or a mesh topology. Cisco Small Business RV0xx Series Routers Administration Guide 170
