Can a downstream terminal connected to an AR obtain an IP address through DHCP
A downstream terminal connected to the AR obtain an IP address through DHCP in either of the following situations: - The AR is configured with the DHCP server function. By default, an AR is not configured with the DHCP server function. - Another DHCP server exists on the network and there is a reachable route from the terminal to the DHCP server.
