[c-nsp] Client DHCP Server

[Mohammed Dado]

I've tried  turning of the DHCP server on the wifi routers, but there's a problem in some of them that the option of turning this service off is already missed. What about using some supported features by the ISP-router to stop this DHCP requests from happening ?

As you probably know, a DHCP server without some getting some help from
the routers is only going to serve addresses on the network it's located
on.  Assuming this is on the customer prem, you're probably not going to
see them at the 7500 end.  Do you have a topology diagram?  Any reason
you can't tell the customers to turn off DHCP server on the wifi
routers?  Unless you've got a DHCP-snooping-capable switch located on
each customer network, you probably can't use that.

Access NW is WiMAX. Cisco hardware at the ISP end is Cisco 7500 Series.

Before anyone can try to speculate on how to solve such a problem,
you'll
need to provide more information, such as what the access network
technology
is, what Cisco hardware you have at the "ISP end".
