Dear Team,
I am currently using IKEv1 for my site-to-site IPsec VPN between Cisco routers, utilizing a DDNS service from DynDNS (xxx.dyndns.com) at the Head Office (HO). All my remote sites are configured to connect to the HO using this DDNS. The VPN is functioning perfectly.
I am planning to replace my existing HO router with MX105. I need to support both IKEv1 and IKEv2 because the old routers only support IKEv1, while some of the new 900 series routers support IKEv2. On the new router, I would like to discontinue IKEv1 and configure IKEv2 to connect with the HO.
I have searched through various posts but have not found any specific guidance on configuring IKEv2 with a DDNS peer for a site-to-site IPsec VPN. I would appreciate any support or configuration examples you could provide for setting this up.
Thank you for your assistance.
