Dynamic Multipoint VPN

This wizard assists you to configure a Dynamic Multipoint VPN (DMVPN) hub or spoke. A typical VPN configuration is a point-to-point IPsec tunnel between two routers. DMVPN creates a network with a central hub that connects to multiple spokes using GRE over an IPsec tunnel.

To configure a DMVPN hub, complete the following tasks in the wizard:

1. Specify the network topology. The network topology may be hub-and-spoke network or fully meshed. The hub-and-spoke option is used if the network has all spoke routers as point-to-point connections to a hub router. A fully meshed DMVPN configuration allows the spoke to establish direct IPsec tunnels to each other. A multipoint GRE tunnel is configured on the spoke to support this functionality. Support for a fully meshed VPN is available starting in Cisco IOS Software Release 12.3(T). Figure 23-26 shows the DMVPN Network Topology screen.
