1. Introduction
1. 介绍

Before a mobile node can engage in Mobile IPv6 signaling with a home agent, it should either know the IP address of the home agent via pre-configuration or dynamically discover it. The Mobile IPv6 specification [RFC6275] describes how home agents can be dynamically discovered by mobile nodes that know the home network prefix. This scheme does not work when prefix information is not already available to the mobile node. This document specifies extensions to DHCPv6 [RFC3736] [RFC3315] to deliver the home agent information to the mobile node in the form of the IP address of the home agent or the Fully Qualified Domain Name (FQDN) [RFC1035] of the home agent. The information delivered to the mobile node may also include the home prefix for the mobile node. The solution involves defining new DHCP options to carry home network prefixes, home agent IP addresses, and FQDN information. The mobile node MAY also use the home prefix to discover the list of home agents serving the home prefix using the Dynamic Home Agent Address Discovery mechanism specified in [RFC6275].

在移动节点可以与归属代理进行移动IPv6信令之前,它应该通过预配置知道归属代理的IP地址,或者动态地发现它。移动IPv6规范[RFC6275]描述了知道家庭网络前缀的移动节点如何动态发现家庭代理。当前缀信息对移动节点不可用时,此方案不起作用。本文档指定对DHCPv6[RFC3736][RFC3315]的扩展,以归属代理的IP地址或归属代理的完全限定域名(FQDN)[RFC1035]的形式将归属代理信息传递给移动节点。交付给移动节点的信息还可以包括移动节点的归属前缀。解决方案包括定义新的DHCP选项以携带家庭网络前缀、家庭代理IP地址和FQDN信息。移动节点还可以使用归属前缀来使用在[RFC6275]中指定的动态归属代理地址发现机制来发现服务于归属前缀的归属代理的列表。

As part of configuring the initial TCP/IP parameters, a mobile node can find itself a suitable home agent. Such a home agent might reside in the access network to which the mobile node connects or in a home network with which the mobile node is associated. A mobile node can indicate its home network identity when roaming to a visited network in order to obtain the MIPv6 bootstrap parameters from the home network. As an example, the visited network may determine the home network of the mobile node based on the realm portion of the NAI (Network Access Identifier) [RFC4282] used in access authentication [RFC5447].

作为配置初始TCP/IP参数的一部分,移动节点可以找到自己合适的归属代理。这样的归属代理可以驻留在移动节点所连接的接入网络中,或者驻留在移动节点所关联的归属网络中。移动节点可以在漫游到到访网络时指示其归属网络标识,以便从归属网络获取MIPv6引导参数。例如,到访网络可以基于在接入认证[RFC5447]中使用的NAI(网络接入标识符)[RFC4282]的领域部分来确定移动节点的归属网络。

The mobile node may or may not be connected to the "home" network when it attempts to learn Mobile IPv6 home network information. This allows operators to centrally deploy home agents while being able to bootstrap mobile nodes that are already roaming. This scenario also occurs when Hierarchical Mobile IPv6 (HMIPv6) [RFC5380] is used, where the mobile node is required to discover the MAP (a special home agent) that is located multiple hops away from the mobile node's attachment point.

当移动节点尝试学习移动IPv6家庭网络信息时,它可以连接到“家庭”网络,也可以不连接到“家庭”网络。这允许运营商集中部署归属代理,同时能够引导已经漫游的移动节点。当使用分层移动IPv6(HMIPv6)[RFC5380]时,这种情况也会发生,其中移动节点需要发现距离移动节点的连接点多个跃点的MAP(特殊归属代理)。

3. DHCP Options for Home Network/Agent Dynamic Discovery
3. 家庭网络/代理动态发现的DHCP选项

This section introduces new DHCP options that are used for dynamic discovery of the home agent's IPv6 address, IPv6 home network prefix, or FQDN information in Mobile IPv6. Transport to a home agent over IPv4 is also supported by specifying an IPv4-Embedded IPv6 address. The detailed procedures are described in Section 2.3.2 of "Mobile IPv6 Support for Dual Stack Hosts and Routers" [RFC5555].

本节介绍用于在移动IPv6中动态发现归属代理的IPv6地址、IPv6归属网络前缀或FQDN信息的新DHCP选项。通过指定IPv4嵌入IPv6地址,还支持通过IPv4传输到归属代理。详细程序见“双栈主机和路由器的移动IPv6支持”[RFC5555]的第2.3.2节。

The names of options listed in this section all start with MIPv6, in order to differentiate them from other DHCP options that might have similar names. However, throughout the rest of this document, the options are referred to by name without the MIPv6 prefix, for brevity.

本节中列出的选项名称均以MIPv6开头,以区别于其他可能具有类似名称的DHCP选项。但是,为了简洁起见,在本文档的其余部分中,这些选项都是按名称引用的,没有MIPv6前缀。

3.1. MIPv6 Home Network ID FQDN Option
3.1. MIPv6家庭网络ID FQDN选项

This option is used by mobile nodes to communicate to the DHCP server an FQDN that identifies the target home network for which the client is requesting configuration information. When the mobile node requests configuration for more than one target home network, this option is also used by the server to identify the target home network for each Identified Home Network Information option returned.

移动节点使用此选项与DHCP服务器通信FQDN,该FQDN标识客户端请求配置信息的目标家庭网络。当移动节点请求配置多个目标家庭网络时,服务器还使用此选项为返回的每个已识别家庭网络信息选项识别目标家庭网络。

When a mobile node sends this option to request information about a specific home network, the option is simply included in the DHCP message from the mobile node. When a server responds with an Identified Home Network Information option, this option MUST be encapsulated in the Identified Home Network Information option that it identifies.

当移动节点发送此选项以请求有关特定家庭网络的信息时,该选项仅包含在来自移动节点的DHCP消息中。当服务器响应标识的家庭网络信息选项时,此选项必须封装在其标识的标识的家庭网络信息选项中。

4. Option Usage
4. 期权使用

The requesting and sending of the proposed DHCP options follow the rules for DHCPv6 options in [RFC3315].

建议的DHCP选项的请求和发送遵循[RFC3315]中DHCPv6选项的规则。

4.1. Mobile Node Behavior
4.1. 移动节点行为

Mobile nodes MAY obtain MIPv6 configuration information during either a stateful configuration exchange [RFC3315] or a stateless configuration exchange [RFC3736].

移动节点可在有状态配置交换[RFC3315]或无状态配置交换[RFC3736]期间获取MIPv6配置信息。

Mobile nodes that obtain MIPv6 configuration information using a stateful configuration exchange SHOULD include the same options in every message they send to the DHCP server.

使用有状态配置交换获取MIPv6配置信息的移动节点应在发送到DHCP服务器的每条消息中包含相同的选项。

Mobile nodes that obtain MIPv6 configuration using a stateless exchange MAY omit MIPv6 configuration from some exchanges, but SHOULD reconfigure whenever a change in the attached network is detected. If the DHCP server responds to a MIPv6-related stateless configuration request with an Information Request Timer option, the mobile node SHOULD attempt to reconfigure when the IRT expires.

使用无状态交换获取MIPv6配置的移动节点可能会从某些交换中忽略MIPv6配置,但在检测到连接的网络发生更改时,应该重新配置。如果DHCP服务器使用信息请求计时器选项响应与MIPv6相关的无状态配置请求,则移动节点应在IRT过期时尝试重新配置。

A mobile node using stateless configuration may try to perform home network information discovery when it lacks home network information for MIPv6 or needs to change the home agent for some reason. For example, this may be necessary to recover from the failure of an existing home agent or to use the local home agent located in the network where the mobile node is currently attached. Note that despite the home information discovery procedure, the mobile node may continue to use the old home agent, in order to avoid losing current sessions.

使用无状态配置的移动节点在缺少MIPv6的家庭网络信息或出于某种原因需要更改家庭代理时,可能会尝试执行家庭网络信息发现。例如,这对于从现有归属代理的故障中恢复或使用位于移动节点当前连接的网络中的本地归属代理可能是必需的。注意,尽管有归属信息发现过程,移动节点可以继续使用旧的归属代理,以避免丢失当前会话。

4.1.1. Requesting MIPv6 Configuration
4.1.1. 正在请求MIPv6配置

Mobile nodes signal that they are interested in being configured with MIPv6 home agent information by requesting one or more of the three Home Network Information options: the Visited Home Network Information option, the Identified Home Network Information option, or the Unrestricted Home Network Information option. To request these options, the client lists them in the Option Request Option (ORO). A client that requests any of these three options in the ORO MUST also request the Home Network Identifier FQDN option, the Home Network Prefix option, the Home Agent Address option, and the Home Agent FQDN option.

移动节点通过请求三个家庭网络信息选项(到访家庭网络信息选项、标识的家庭网络信息选项或不受限制的家庭网络信息选项)中的一个或多个来表示他们有兴趣配置MIPv6家庭代理信息。要请求这些选项,客户端会在选项请求选项(ORO)中列出它们。请求ORO中这三个选项中任何一个选项的客户端还必须请求家庭网络标识符FQDN选项、家庭网络前缀选项、家庭代理地址选项和家庭代理FQDN选项。

If the mobile node requests the Visited Home Network Information option, this indicates that it is interested in learning the home

如果移动节点请求访问的家庭网络信息选项,这表示它有兴趣学习家庭信息

network information that pertains to the currently visited network. This type can be used to discover local home agents in the local ASP.

与当前访问的网络相关的网络信息。此类型可用于在本地ASP.NET中发现本地主代理。

If the mobile node requests the Identified Home Network Information option, this indicates that it is interested in learning the home network information that pertains to a specified realm. This type can be used to discover home agents that are hosted by a user's home domain or by any target domain. A mobile node requesting the Identified Home Network Information option MUST include a Client Home Network ID FQDN option identifying the MSP being identified. The target MSP can be a mobile node's home MSP or any MSP that has a trusted roaming relationship with the mobile node's MSA.

如果移动节点请求识别的家庭网络信息选项,则这表示它有兴趣学习属于指定领域的家庭网络信息。此类型可用于发现由用户的主域或任何目标域承载的主代理。请求标识的家庭网络信息选项的移动节点必须包括标识正在标识的MSP的客户端家庭网络ID FQDN选项。目标MSP可以是移动节点的主MSP或与移动节点的MSA具有可信漫游关系的任何MSP。

If the mobile node has no preference as to the home network with which it should be configured, it SHOULD request the Unrestricted Home Network Information option, and SHOULD NOT request either the Visited Home Network Information option or the Identified Home Network Information option.

如果移动节点对其应配置的家庭网络没有偏好,则其应请求无限制家庭网络信息选项,并且不应请求访问的家庭网络信息选项或识别的家庭网络信息选项。

A client that wishes to be configured with both the Visited Home Network Information option and the Identified Home Network Information option may request both options in the Option Request Option. A client may request information about more than one identified domain by requesting the Identified Home Network Information option in the ORO and including more than one Home Network ID FQDN option. A client that sends more than one Home Network ID FQDN option MUST request the Home Network ID option in the ORO.

希望同时配置到访家庭网络信息选项和识别的家庭网络信息选项的客户端可以在选项请求选项中请求这两个选项。客户端可以通过请求ORO中的已识别家庭网络信息选项并包括多个家庭网络ID FQDN选项来请求关于多个已识别域的信息。发送多个家庭网络ID FQDN选项的客户端必须在ORO中请求家庭网络ID选项。

4.1.2. Processing MIPv6 Configuration Information
4.1.2. 处理MIPv6配置信息

DHCP Clients on mobile nodes should be prepared to receive any MIPv6 Home Network Information options they request. If more than one Home Network ID FQDN option was sent, the client should be prepared to handle zero or more Identified Home Network Information options in response; the DHCP server may not have configuration information for all targeted domains, or, indeed, for any. If a misconfigured server returns an Identified Home Network Information option that does not contain a Home Network ID FQDN option corresponding to one that the client requested, the client MUST silently discard that Identified Home Network Information option.

移动节点上的DHCP客户端应准备好接收其请求的任何MIPv6家庭网络信息选项。如果发送了多个家庭网络ID FQDN选项,则客户端应准备处理零个或多个已识别的家庭网络信息选项作为响应;DHCP服务器可能没有所有目标域的配置信息,或者实际上没有任何目标域的配置信息。如果配置错误的服务器返回的标识的家庭网络信息选项不包含与客户端请求的家庭网络ID FQDN选项相对应的家庭网络ID FQDN选项,则客户端必须以静默方式放弃该标识的家庭网络信息选项。

If any of the three Home Network Information options is returned, configuration information will be included within it. The client must be prepared to handle home agent addresses in the form of either the Home Agent Address option or the Home Agent FQDN option.

如果返回三个家庭网络信息选项中的任何一个,配置信息将包含在其中。客户端必须准备好以home agent Address选项或home agent FQDN选项的形式处理home agent地址。

If the client finds an IPv4-Embedded IPv6 address in a Home Agent Address option, it may only use this address to communicate over IPv4. If a Home Network Information option does not contain complete configuration information, the client MUST silently discard that Home Network Information option.

如果客户端在归属代理地址选项中找到IPv4嵌入IPv6地址,则它可能仅使用此地址通过IPv4进行通信。如果家庭网络信息选项不包含完整的配置信息,则客户端必须以静默方式放弃该家庭网络信息选项。

If the client receives any Home Network ID FQDN options, Home Network Prefix options, Home Agent Address options, or Home Agent FQDN options that are not encapsulated in one of the three types of Home Network Information options, it MUST silently discard these options.

如果客户端收到未封装在三种家庭网络信息选项之一中的任何家庭网络ID FQDN选项、家庭网络前缀选项、家庭代理地址选项或家庭代理FQDN选项,则必须以静默方式放弃这些选项。

The DHCP client must pass whatever configuration information it receives to the appropriate mobile IP implementation on the mobile node. How this is done, and what the mobile IP implementation on the mobile node does with this information, is outside the scope of this document.

DHCP客户端必须将其接收到的任何配置信息传递给移动节点上的相应移动IP实现。如何做到这一点,以及移动节点上的移动IP实现如何利用这些信息,超出了本文档的范围。

As described later in this section, servers may provide more than one Home Network Information option or multiple Home Agent Prefix, Home Agent Address, or Home Agent FQDN options. When provided with multiple Visited Home Network Information options or Unrestricted Home Network Information options of the same type, or with multiple sub-options within such an option, the mobile node SHOULD choose the first one that it can employ.

如本节后面所述,服务器可以提供多个家庭网络信息选项或多个家庭代理前缀、家庭代理地址或家庭代理FQDN选项。当向移动节点提供多个到访家庭网络信息选项或相同类型的不受限制的家庭网络信息选项时,或者在该选项中提供多个子选项时,移动节点应选择其可以使用的第一个选项。

If the DHCP client on a mobile node receives any Home Network Prefix options, Home Agent Address option, or Home Agent FQDN option that are not contained within Home Network Information options, the DHCP client MUST silently discard these options.

如果移动节点上的DHCP客户端接收到家庭网络信息选项中未包含的任何家庭网络前缀选项、家庭代理地址选项或家庭代理FQDN选项,则DHCP客户端必须以静默方式放弃这些选项。

4.2. Relay Agent Behavior
4.2. 中继代理行为

In some cases, DHCP relay agents may have access to configuration information for the mobile node. In such cases, relay agents MAY send Visited Home Network Information options, Identified Home Network Information options, and/or Unrestricted Home Network Information options to the DHCP server. To do so, the relay agent MUST encapsulate these options in a Relay-Supplied Options option [RFC6422]. If the DHCP relay agent includes any Identified Home Network Information options, these options MUST correspond to home networks identified in Home Network ID FQDN options in the client request. In addition, each Identified Home Network Information option must contain a Home Network ID FQDN option identical to the one sent by the client, to identify the network to the client.

在某些情况下,DHCP中继代理可以访问移动节点的配置信息。在这种情况下,中继代理可以向DHCP服务器发送到访家庭网络信息选项、识别的家庭网络信息选项和/或不受限制的家庭网络信息选项。为此,中继代理必须将这些选项封装在中继提供的选项[RFC6422]中。如果DHCP中继代理包括任何标识的家庭网络信息选项,则这些选项必须对应于客户端请求中的家庭网络ID FQDN选项中标识的家庭网络。此外,每个已标识的家庭网络信息选项必须包含与客户端发送的相同的家庭网络ID FQDN选项,以便向客户端标识网络。

No special handling is required when processing relay-reply messages.

处理中继回复消息时不需要特殊处理。

4.3. DHCP Server Behavior
4.3. DHCP服务器行为

Generally, DHCP servers can simply be configured with Visited Home Network Information options, Identified Home Network Information options, and Unrestricted Home Network Information options. In the case of Visited Home Network Information options and Unrestricted Home Network Information options, which clients get what options depends on operator configuration.

通常,DHCP服务器可以简单地配置访问的家庭网络信息选项、已识别的家庭网络信息选项和不受限制的家庭网络信息选项。在访问家庭网络信息选项和不受限制的家庭网络信息选项的情况下,哪些客户端获得什么选项取决于运营商配置。

A DHCP server MAY maintain a table of Home Network ID FQDNs. For each such FQDN, a server that maintains such a table SHOULD include an Identified Home Network Information option. Such a server would look up the FQDN from any Home Network ID FQDN options provided by the client in its table, and for each match, include the Identified Home Network Information option configured in the table entry for that FQDN.

DHCP服务器可以维护家庭网络ID FQDNs表。对于每个这样的FQDN,维护这样一个表的服务器应该包括一个标识的家庭网络信息选项。这样的服务器将从客户机在其表中提供的任何家庭网络ID FQDN选项中查找FQDN,并且对于每个匹配项,包括在该FQDN的表条目中配置的已标识家庭网络信息选项。

If a DHCP server does not implement the Home Network ID FQDN table, or some similar functionality, it is an error for the operator to configure it with any Identified Home Network Information options. These options could be erroneously forwarded to the client, which would have no use for them, and is required to discard them.

如果DHCP服务器未实现家庭网络ID FQDN表或某些类似功能,则操作员使用任何已识别的家庭网络信息选项对其进行配置是错误的。这些选项可能会被错误地转发给客户机,而客户机对这些选项没有任何用处,因此需要放弃这些选项。

DHCP servers that implement the Home Network ID FQDN table must, when sending an Identified Home Network Information option to the client, include a Home Network ID option within the Identified Home Network Information option that identifies the home network for which configuration information is being sent.

在向客户端发送标识的家庭网络信息选项时,实现家庭网络ID FQDN表的DHCP服务器必须在标识的家庭网络信息选项中包含一个家庭网络ID选项,该选项标识要为其发送配置信息的家庭网络。

Aside from the Home Network ID FQDN table, the actual behavior of the DHCP server with respect to MIPv6 configuration is simply in accordance with the DHCPv6 protocol specification [RFC3315] and depends on operator configuration. No special processing is required for Visited Home Network Information options or Unrestricted Home Network Information options.

除了家庭网络ID FQDN表之外,DHCP服务器关于MIPv6配置的实际行为仅符合DHCPv6协议规范[RFC3315],并取决于操作员配置。访问的家庭网络信息选项或不受限制的家庭网络信息选项不需要特殊处理。

4.4. Home Agent Discovery Using a Network Access Server
4.4. 使用网络访问服务器的归属代理发现

[RFC5447] describes the complete procedure for home agent assignment among the mobile node, NAS (Network Access Server), DHCP, and Authentication, Authorization, and Accounting (AAA) entities for the bootstrapping procedure in the integrated scenario.

[RFC5447]描述了集成场景中引导过程的移动节点、NAS(网络访问服务器)、DHCP和身份验证、授权和计费(AAA)实体之间归属代理分配的完整过程。

A NAS is assumed to be co-located with a DHCP relay agent or a DHCP server in this solution. In a network where the NAS is not co-located with a DHCP relay or a server, the server may not be provided with the home network information from the NAS; therefore,

在此解决方案中,假定NAS与DHCP中继代理或DHCP服务器位于同一位置。在NAS与DHCP中继或服务器不位于同一位置的网络中,可以不向服务器提供来自NAS的家庭网络信息;因此

it may either fail to provide information or provide home information that has been pre-configured by the administrator or that is acquired through a mechanism that is not described in this document.

它可能无法提供管理员预先配置的信息或通过本文档中未描述的机制获取的主页信息。

5. Security Considerations
5. 安全考虑

Secure delivery of home agent and home network information from a DHCP server to the mobile node (DHCP client) relies on the same security as DHCP. The particular option defined in this document does not have additional impact on DHCP security.

从DHCP服务器到移动节点(DHCP客户端)的归属代理和归属网络信息的安全传递依赖于与DHCP相同的安全性。本文档中定义的特定选项对DHCP安全性没有其他影响。

Aside from the DHCP client-to-server interaction, an operator must also ensure secure delivery of mobile IP information to the DHCP server. This is outside the scope of DHCP and the newly defined options.

除了DHCP客户端到服务器的交互之外,运营商还必须确保将移动IP信息安全地传送到DHCP服务器。这超出了DHCP和新定义的选项的范围。

The mechanisms in this specification could be used by attackers to learn the addresses of home agents in the home network or to feed incorrect information to mobile nodes.

攻击者可利用本规范中的机制了解家庭网络中家庭代理的地址,或向移动节点提供不正确的信息。

The ability to learn addresses of nodes may be useful to attackers because brute-force scanning of the address space is not practical with IPv6. Thus, they could benefit from any means that make mapping the networks easier. For example, if a security threat targeted at routers or even home agents is discovered, having a simple mechanism to easily find out possible targets may prove to be an additional security risk.

学习节点地址的能力可能对攻击者有用,因为对地址空间进行暴力扫描在IPv6中不实用。因此,他们可以从任何使网络映射更容易的方法中获益。例如,如果发现针对路由器甚至家庭代理的安全威胁,那么使用简单的机制轻松找到可能的目标可能会带来额外的安全风险。

Apart from discovering the address(es) of home agents, attackers will not be able to learn much from this information, and mobile nodes cannot be tricked into using wrong home agents, as the actual communication with the home agents employs mutual authentication.

除了发现归属代理的地址外,攻击者将无法从该信息中了解更多信息,并且移动节点也不会被诱骗使用错误的归属代理,因为与归属代理的实际通信采用了相互认证。

The mechanisms from this specification may also leak interesting information about network topology and prefixes to attackers, and where there is no security to protect DHCP, even modify this information. Again, the mobile nodes and home agents employ end-to-end security when they communicate with each other. The authentic source of all information is that communication, not the information from DHCP.

此规范中的机制还可能向攻击者泄漏有关网络拓扑和前缀的有趣信息,并且在没有安全保护DHCP的情况下,甚至可以修改此信息。同样,移动节点和归属代理在彼此通信时采用端到端安全性。所有信息的真实来源是通信,而不是来自DHCP的信息。

However, attacks against the information carried in DHCP may lead to denial of service if mobile nodes are unable to connect to any home agent, or choose a home agent that is not the most preferred one.

但是,如果移动节点无法连接到任何归属代理,或者选择一个不是最首选的归属代理,那么针对DHCP中携带的信息的攻击可能会导致拒绝服务。
