Or I should interpret those commands a little bit different like below?
1. DHCP and bootp:
service dhcp
2. DHCP and no bootp
service dhcp
no ip bootp server
3. DHCP and option to have bootp
service dhcp
ip dhcp ignore bootp (globally)
ip helper-address < > ; if you want to forward bootp, use the
interface command of "ip helper-address" to override global ignore
option.

Reading an old post and have a question. If we want to disable both dhcp
and bootp, we use "no service dhcp". If we just want to have DHCP but
not bootp, we can use "service dhcp; ip dhcp bootp ignore". My question
is, in what situation, do we need to use "no ip bootp server"?
Thanks.
