Hey, thanks a lot for your reply.
However, there are two things that needs more clarification:
1> I understand both MX ports have inbuilt default route toward default gateway(that we configure) so as soon as ports are assigned with IP addresses(Pulbic and Private) they would send the Internet traffic to their default gateway(by default feature) to make connection with VPN registry. Is this right? or we need to point some static entry in MX for default route. IF yes then how.
2> how the branch MPLS port is going to make auto vpn with HUB site when it has no direct route for Internet as private IP is configured to this port? I mean what configure is required so this private IP can reach out to Meraki cloud and then it allows to build the auto vpn with HUB site.
3> Do both branch ports make the auto vpn tunnel with all the wan ports at hub site like branch Internet to HUB internet port, branch Internet to HUB MPLS, branch MPLS to HUB internet and branch MPLS to HUB MPLS
It would be great if you can tell me about them as well.
