GRE Tunnel Group Profile

A GRE Tunnel Group profile consists of two tunnels on a managed device, one active and one standby. If the active tunnel fails, the standby tunnel takes over. If the standby also fails, a third tunnel can then assume control. Preemption, enabled by default, allows traffic to automatically redirect to a higher-priority tunnel when detected. If preemption is disabled, traffic will only redirect to a higher-priority tunnel if the currently active tunnel fails.

Note:

IPv6 GRE tunnel is not supported in tunnel group. Hence, you cannot add Layer-2 or Layer-3 GRE tunnels to a tunnel group.
