Abstract

The Point-to-Point Protocol (PPP) [1] provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP defines an extensible Link Control Protocol and a family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.

Abstract

The Point-to-Point Protocol (PPP) [1] provides a standard method for

transporting multi-protocol datagrams over point-to-point links. PPP

defines an extensible Link Control Protocol and a family of Network

Control Protocols (NCPs) for establishing and configuring different

network-layer protocols.

This document extends the NCP for establishing and configuring the

Internet Protocol over PPP [2], defining the negotiation of primary

and secondary Domain Name System (DNS) [3] and NetBIOS Name Server

(NBNS) [4] addresses.

1. Additional IPCP Configuration Options

The four name server address configuration options, 129 to 132,

provide a method of obtaining the addresses of Domain Name System

(DNS) servers and (NetBIOS Name Server (NBNS) nodes on the remote

network.

Primary and secondary addresses are negotiated independently. They

serve identical purposes, except that when both are present an

attempt SHOULD be made to resolve names using the primary address

before using the secondary address.

For implementational convenience, these options are designed to be

identical in format and behavior to option 3 (IP-Address) which is

already present in most IPCP implementations.

Since the usefulness of name server address information is dependent

on the topology of the remote network and local peer's application,

it is suggested that these options not be included in the list of

"IPCP Recommended Options".
