Re: IP DHCP option12

mantzubav · ‎11-16-2018

Hi,

after creating DHCP service on ISR 1100 we have noticed that all hostnames on MACs are changed by DHCP server. Now hostnames seems to mixture from Public IP and public DNS name. Is there any way to disable this feature? It was working fine with other vendor firewall.

Thanks!

If i understand correctly, you looking to disable option 12 in the new ASR where you created DHCP Service ?

or you looking to disable DHCP Service ?
