VPN Mesh Topology
In a VPN mesh topology, each VPN router can communicate securely with all other
VPN routers. Multiple secured tunnels extend from each site to all other sites.
In the following example, four sites are connected in a VPN mesh topology. Three
VPN tunnels extend from each site, providing secure communications with all
other sites. Data can travel directly between any two sites.

This topology requires much more configuration on each router. However, it works
well in a complicated network with data traveling between multiple sites. Because
all devices have direct peer relationships with one another, this design prevents
the bottlenecks that can occur with a hub-and-spoke topology. This design also
ensures that if one site is down, the other sites can continue to exchange data.
NOTE When the number of nodes in a full mesh topology increases, scalability may
become an issue—the limiting factor being the number of tunnels that the devices
can support at a reasonable CPU utilization.
