after replacing router with new one, VPN start to work after24h

[kruno]

I started to replace my old Cisco 881 with C921 routers, using the same config, VPN starts to work after, I think, 24h.

Is there a way to speed it up manually?

I'm using DMVPN, tunnel is up, can ping IPs from both ends of a tunnel but this is it, no ping to other sites/computers, EIGRP don't propagate this tunnel.

  - @kruno      Start by examining and collecting logs on the  C921   . E.g:    what is different when the VPN starts working ?
