Have an existing ATM network. Looking to add another WAN link that we can do DMVPN mesh network with the other branches. There are a total of 8 branches. What would be the ISR recommendation for the branches? Comparing the 1841 and the 2811. Is the AIM-VPN recommended and the AIM-ATM? Is the AIM-ATM supported in the 1841? Please confirm that the AIM-ATM is required to run ATM on an ISR.
I have this problem too.
