I am working on understanding GET vpn. I want to ask few questions:
1) Suppose i have 4 spoke (branches) and one HUB site. With GET VPN spokes are authenticates with hub (key server) and then get security policies and then form VPN with HUB dynamically.It means we dont need to form static vpn tunnels from spokes to hub. DMVPN provides spoke to spoke dynamic VPN tunnel and GET vpn provides spoke to hub dynamic vpn tunnel. Am i right in understanding? But how about routing from spoke to hub and from spoke to spoke? It can be dynamic?
2) GET VPN is tunnel less which preserve the multicast header. But if we have internet between branches and hub then internet does not support routing of multicast traffic. It means GET vpn is beneficial if we have privte WAN?
