ISIS? What is this, the 90s? GRE tunnels and IPsec seem like a lot of overhead. I'd keep it simple with DMVPN.

Full mesh OSPF with IPsec tunnels? Sounds like a lot of manual configuration at the remote sites. I'd go for something more plug-and-play.

MPLS? Really? That's overkill for this requirement. We need something more straightforward and cost-effective.

Dual DMVPN with EIGRP routing seems like the way to go. It provides redundant paths and auto path selection - perfect for this scenario.

I disagree. I believe option C) full mesh OSPF with IPsec tunnels would be a better choice for supporting IP multicast.

I agree with Janessa. DMVPN provides secure connectivity and EIGRP allows for redundant paths.
