Chapter 8 Management Network Connectivity

IP Addressing Scenarios

In the example, the GNE is assigned an IP address within the central office LAN and is physically connected to the LAN through its LAN port. ENEs are assigned IP addresses that are outside the central office LAN and given private network IP addresses. If the ENEs are collocated, the LAN ports could be connected to a hub. However, the hub should have no other network connections.
