OK, I'm starting to see where the confusion is coming from. The "ip
dhcp-server" command can be used on dial-up PPP links. It specifies the IP
address of a DHCP server for the PPP client to use. It was almost
impossible to find in the documentation. Most of the ip dhcp commands
relate to telling your router to be a DHCP server, which is a completely
different solution, of course.
Are you using PPP, Khramov?
The general-purpose way to tell your router the address of your DHCP server
is the ip helper-address command.
