| + | |
| + | At this point, the basic DMVPN configuration is complete and phase 3 will now take effect in order to dynamically establish connectivity between spokes. Using this method, additional spokes may be configured and added to the current topology. DMVPN Phase 3 technology will ensure that any newly introduced devices will be included in the final topology. |
