Hi All
We got 2 VPN Hub Server and 25 Spokes. Few spokes terminate VPN on ASA as they dont have Router. We are looking at the option of moving to DMVPN. For migrating from tradional IPSEC / GRE VPN to DMVPN what are the expected issues or concerns. can we have DMVPN on the same Router as the existing IPSEC tunnel / GRE Tunnel. Hub Routers are 3800 series and Branch Routers are mix of 2800,1800,ASA,887 series.
Please input
thanks
