Hi, i have a partner who wants to connect its single site with our 2 sites using ethernet over fiber. They have an ip pool which conflicts with an already ip pool advertised in our network. Our suggestion of implenting NAT has already been rejected due to some unknown reasons. They have suggested implementing GRE tunnel, which in my own opinion is worthless and also complicated in implemented 2 GRE tunnels from my side. I need to know if there is any better ides to achieve this connectivity. we will run OSPF with them, with their site area being stub.
I have this problem too.
