Running DHCP over PPP interface

[Dutta, Ashutosh]

Glenn thanks for your email. The applicability has been discussed in pppext mailing list. It was suggested to use PPP to obtain IP address and use DHCP to obtain the server address (e.g., SIP server etc.). This could be applicable in a CDMA2000 environment.
 
In my case, I use PPP to obtain an IP address from the PPP server and use DHCP to obtain other server related information. Thus PPP server can act like a relay or DHCP server can always co-exist with the PPP server as well. At this time when we run dhclient -d ppp0, the DISCOVER packet gets garbled and never reaches the PPP server also. 
 
Thanks
Ashutosh

Typically PPP interfaces use the PPP link control protocol (LCP) to
acquire an IP address from the other end. I don't think DHCP will ever
work in this situation.

What typically happens on the 'server' end is that the remote
access server might be configured to make a dhcp request and
then use PPP-LCP to transmit this IP address to the other end of
the PPP link.

Perhaps a little more detail on what you are trying to achieve
might assist?
