How a pppoe subscriber with static ip sends ipcp configure request. For dhcp the subscriber can include in configure request of ipcp packet and obtain its ip from remote server. But in static ip case, will it work only if subcriber always sends its fixed ip? Can ipcp support static ip like dhcp?

  • Depends on the ISP setup. Some will always return the static address no matter what you ask for -- zero or the actual address. Others will only return the static if asked for. (Bellsouth used to require %static on the username to activate one's static address)

IPCP for PPPoE is the same as with serial PPP - check RFC 1332.

A peer sends a Configure-Request (type 3) containing the desired IP address which the other side then either Configure-Acks or Configure-Naks. The address requests any address.
