Dear Team, After struggling to establish the VPN connection between the Cisco 800 IKEV1 and 900 series with Meraki MX105, we experienced tunnel drops every 10 hours. To address this issue, we enabled track reachability to identify the peer state when it goes down, which helps clear the crypto sessions and allows all tunnels to function properly again. Now, everything is working successfully. However, the Cisco 900 configured with IKEv2 is also showing some issues, and I have logged a case with Cisco TAC. We are currently awaiting their R&D team for a solution. Thank you, everyone. I will keep you updated on any developments.
