I am exploring the idea of DMVPN. Currently I have about 15 sites on Cisco 2811 ISR routers connected to an ASA at the HQ on an IPSEC vpn. This number is expect grow to over 30. I'd like to incorporate a fully meshed vpn terminated back to a Cisco 3825 that is behind the ASA for branch to HQ traffic. Any docs or suggestions concerning this would be appreciated.
My experience with DMVPN has been smooth - I migrated connections from VPN 3K Concentrator to a 3825. Setup a single hub with multiple spokes. EIGRP neighbor connections up and runningâ¦ I used DMVPN as a backup link - so each spoke has two links back to the main office. Once you have the hub setup and a single spoke - easy to roll out other sites. The guides offer step by step and great examples.
