How do I configure multi sites to sites VPN?

I have one sonicwall 2040 pro with SonicOS Enhanced and 7 sonicwall 170 sp. I want to set up Multisite VPN from 170 sp to 2040. There is no server invole just site to site VPN. Is this possible can be done with out any extra VPN  software or hardware.The perfect condition is all site can comunicate with each other is possible but the most import thing I try to accomplish is all internal network from 2040 pro can communicate with any network behind 170 sp
Lan IP for 2040 pro is 192.168.0.0
Lan IP for 170 sp is 192.168.y.0 where y is stand for site 1,2 3 4 5 6 and 7

Thank you for all help.

The easiest way would be to setup a VPN policy to each remote site from the main site of the 2040. That would allow all remote sites to communicate with the main site. Now for the remote sites to talk to each other, you would have to setup what's call a hub and spoke VPN. I've attached files on how to do this.
