> To provide a level of resiliency in the VPN design, Cisco recommends that at least two tunnels be configured on each branch. Each branch router should have a tunnel to a primary headend, and an alternate tunnel to a secondary headend. Under normal operating conditions, both the primary and secondary tunnels have routing protocol neighbors established. The routing protocol maintains both paths, with the secondary tunnel being configured as a less preferred path.
> If a failure occurs at one of the headend devices, the routing protocol detects that the route through the primary tunnel is no longer valid and, after convergence, the route through the secondary tunnel is used. When the primary is available again, traffic is routed back to the primary tunnel because it is the preferred route in the routing metrics.
