Address and then the overlay address which is what we just called the tunnel address where the MBP an address so the way that specifically this ingoing to work is that the now once the basic configuration is done the spokes are going to dynamically register with the harbor and this is one of the other big skill ability 70-413 techniques have Deion bum is that the hub does not need to know inadvance who are the spokes that belong to the network so on the hob with 27 very basic conveyed that says this is my IP network on the GRE tunnel the GRE tunnel is going to be multipointGRE and then I am the next hops server for and in a chirpy the next time resolution protocol so the next up server is basically listening for the spokes to dynamically register so the spokes will know statically what the IP address of.
