is it possible to run DMVPN on 7606 without ipsec module??

[blackhat2020]

Hi every one,we have  7606 router without any ipsec module on it,so i check the ios and it has all commands in interface tunnel for configuring the dmvpn multipoint tunnel and also protection profile for ipsec! so i have this question: do we can run dmvpn between this router and our wan routers wich are 3845 which im not worry about theme(cause they can for sure)? thanks in advance.

I guess you can but the transmission rates are lower because the router's CPU will do the encryption and other normal function.

Hi,

Both 7600 and 6500 do not support IPsec VPN without VPN SPA or VPNSM (EOL announced), with the exception of management access (long time ago)

It's documented here:

I would say, save yourself the trouble and effort :-)
