Abstract

   This document describes four options for Network Information Service
   (NIS) related configuration information in Dynamic Host Configuration
   Protocol for IPv6 (DHCPv6): NIS Servers, NIS+ Servers, NIS Client
   Domain Name, NIS+ Client Domain name.

1.  Introduction

   This document describes four options for passing configuration
   information related to Network Information Service (NIS) [3] in
   DHCPv6 (RFC 3315 [1]).

   The options defined in this document can only be used to configure
   information about NIS servers that can be reached using IPv6.  The
   DHCP option to configure information about IPv4 NIS servers can be
   found in RFC 2132 [4].  Mechanisms for configuring IPv4/IPv6 dual-
   stack applications are being considered, but are not specified in
   this document.

2.  Terminology

   The key words MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD,
   SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL in this document are to be
   interpreted as described in BCP 14, RFC 2119 [2].

RFC 3898          NIS Configuration Options for DHCPv6      October 2004

   Throughout this document, unless otherwise specified, the acronym
   DHCP refers to DHCP as specified in RFC 3315.

   This document uses terminology specific to IPv6 and DHCP as defined
   in section "Terminology" of RFC 3315.

3.  Network Information Service (NIS) Servers Option

   The Network Information Service (NIS) Servers option provides a list
   of one or more IPv6 addresses of NIS servers available to the client.
   Clients MUST treat the list of NIS servers as an ordered list.  The
   server MAY list the NIS servers in the order of preference.

   The format of the Network Information Service Servers option is as
   shown below:

    0                   1                   2                   3
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   |      OPTION_NIS_SERVERS       |         option-len            |

   |                                                               |
   |                   NIS server (IPv6 address)                   |
   |                                                               |
   |                                                               |

   |                   NIS server (IPv6 address)                   |
   |                                                               |
   |                                                               |
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   |                              ...                              |
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

   option-code:  OPTION_NIS_SERVERS (27)

   option-len:   Length of the 'NIS server' fields in octets; It must be
                 a multiple of 16

   NIS server:   IPv6 address of NIS server

4.  Network Information Service V2 (NIS+) Servers Option

   The Network Information Service V2 (NIS+) Servers option provides a
   list of one or more IPv6 addresses of NIS+ servers available to the
   client.  Clients MUST treat the list of NIS+ servers as an ordered
   list.  The server MAY list the NIS+ servers in the order of
   preference.

   The format of the Network Information Service V2 (NIS+) Servers
   option is as shown below:

    0                   1                   2                   3
