Usage Guidelines
Usage Scenario
When a remote address pool is used for address allocation, if the DHCP server can only respond with a packet carrying the GiAddr address and not the source IP address, the double gateway solution must be used. To specify an IP address in the address pool to function as the GiAddr address, run the dhcp-server giaddr ip-address command. The IP address specified cannot be the same as the gateway address of the address pool.
The DHCP server cannot allocate the GiAddr address to any terminal.Precautions
The GiAddr address specified by ip-addr cannot conflict with any user IP address.
