CISCO 1921 Slow To Boot at First Startup

Hi,

We have some CISCO 1921 with IPSEC VPN and DMVPN Tunnel.

We have around 18 IPSEc Tunnel with Netgear Router.

When I Turn the Power Switch OFF and Back ON the Router take Around 15 Minutes before the Computer in the network are able to Access the Network.

What append is't when the Router Boot, It try first to resolve the peer AAAAAA.getmyip.com dynamic IP Address from the DNS, but the thing that look like that the WAN-1 Interface in the boot sequence go up only after the router try to resolve the 18 peer address xxxxxx.getmyip.com .

The consequence of That is a delay of 15Minutes before the router finish booting.

Is there a Way that the Router First activate the WAN and LAN interface and after try to resolve the xxxxxx.getmyip.com IP Address on the boot sequence ?

If anyone have an idea, please let me know.

See exemple bellow

crypto map Netgear 1 ipsec-isakmp
 set peer AAAAAA.getmyip.com dynamic
 set transform-set Netgear
 set pfs group2
 match address 101
crypto map Netgear 2 ipsec-isakmp
 set peer BBBBBB.getmyip.com dynamic
 set transform-set Netgear
 set pfs group2
 match address 102
crypto map Netgear 3 ipsec-isakmp
 set peer CCCCCC.getmyip.com dynamic
 set transform-set Netgear
 set pfs group2
