WebI have a DMVPN connection in the lab and the highest throughput I am getting is 12Mb/s. Does anyone know what could be causing the bottleneck or lower throughput. My set up looks like this: PC1-->Cisco 3560 switch-->Cisco 2811 router ---VPN tunnel --->Cisco 3560 simulating Internet-->VPN tunnel --->Cisco 2801 router -->Cisco 3560 switch--->PC2 WebIn my experience with DMVPN + QoS I needed to disable anti-replay (especially at the hub), as the maximum window size couldn't account for the packet re-ordering. That appears not to be the problem here. u/miller-net I can't picture how high jitter might cause the IKE SA to go stale; packet loss or IOS bug seems more likely to me.

WebIntroduction to DMVPN. DMVPN (Dynamic Multipoint VPN) is a routing technique we can use to build a VPN network with multiple sites without having to statically configure all devices. It’s a “hub and spoke” network where the spokes will be able to communicate with each other directly without having to go through the hub. WebDMVPN has three phases that route data differently. Phase 1: All traffic flows from spokes to and through the hub. Phase 2: Start with Phase 1 then allows spoke-to-spoke tunnels based on demand and triggers. Phase 3: Starts with Phase 1 and improves scalability of and has fewer restrictions than Phase 2.
