12.2 DHCP reservation
12.2.1 Overview
Through the DHCP reservation function, specified clients can always obtain the same IP address

and other functions can function normally. This function takes effect only when the DHCP server
function of the router is enabled.
To access the configuration page, log in to the web UI of the router, and choose System Settings >
