Hello their friends from cisco,
Can someone help me resolving my issue on DMVPN setup i can't make it stable since 2 weeks as i am experiencing high latency and intermittent ping from head office to just 1 branch office, if i have a small traffic on my dmvpn works very well! but when all users on my network start working at the same time the problem will come up!
I got 1 hub router with 2 ISP with different tunnel interface and different physical interface for redundancy purposes, same thing on the spoke side 2 ISP with different tunnel and physical interface.
I uploaded here my Sho tech- result with public IP changed..
Hope someone will give any feedback to resolve this issue..
Thank you and Merry Christmas to all!!

When running a VPN over the Internet, your VPN is subject to whatever the underlying Internet delays are. These might be seen by pinging, concurrently, "outside of" your VPN at the same time.
From what you described, since it appears volume related, to your own traffic, it might just be you're oversubscribing the available bandwidth. If so, the issue you're seeing would be expected. Also if so, stability and consistency might be improved by using QoS.

i think bandwidth is not the issue, because we just moved from our old linux based router (sparc) to cisco 1941 with dmvpn setup using the same bandwidth and speed, our vpn on our old router is far better than running cisco with dmvpn setup.. mayber there is something wrong on my configuration or something is missing.. please help!
