The use of the Configuration Option IP-Addresses has been deprecated. It has been determined through implementation experience that it is difficult to ensure negotiation convergence in all cases using this option. RFC 1172 [7] provides information for implementations requiring backwards compatability. The IP- Address Configuration Option replaces this option, and its use is preferred.
This option SHOULD NOT be sent in a Configure-Request if a Configure-Request has been received which includes either an IP- Addresses or IP-Address option. This option MAY be sent if a Configure-Reject is received for the IP-Address option, or a Configure-Nak is received with an IP-Addresses option as an appended option.
Support for this option MAY be removed after the IPCP protocol status advances to Internet Draft Standard.
