Dynamic VPN - is when one end of the VPN is unkown, e.g no static IP address. Also you do not know the remote end IP subnet for the encryption domain - so this is learnt at time of VPN creation.

Site-2-Site is typically when you have 2 devices with static IP addresses. You also know the IP subnets at both sites, and configure the encryption domains accodringly.

I may be completely wrong here .. but I don't think a pix 515 can participate in a DMVPN. For a DMVPN to work you'll need to use GRE/IPSEC.

This will enable you to use routing protocols and NHRP.
