If-Match - HP MSR Series Command Reference Manual

export-route: Binds the gateways to the device's MAC address in the address management module. The
ARP module will use the entries to reply to ARP requests from the DHCP clients. This feature ensures the
clients to obtain different gateway IP addresses but the same MAC address.
Usage guidelines
If you use this command multiple times, the most recent configuration takes effect.
If you do not specify any parameters, the undo gateway-list command deletes all gateway addresses.
The DHCP server assigns gateway addresses to clients on a secondary subnet in the following ways:
If gateways are specified in both address pool view and secondary subnet view, DHCP assigns
•
those specified in the secondary subnet view.
If gateways are specified in address pool view but not in secondary subnet view, DHCP assigns
•
those specified in address pool view.
Examples
# Specify the gateway address 10.1.1.1 in DHCP address pool 0.
<Sysname> system-view
[Sysname] dhcp server ip-pool 0
[Sysname-dhcp-pool-0] gateway-list 10.1.1.1
