This document defines a YANG data model [RFC7950] for management of IP implementations.
本文档定义了一个用于管理IP实现的数据模型[RFC7950]。
The data model covers configuration of per-interface IPv4 and IPv6 parameters as well as mappings of IP addresses to link-layer addresses. It also provides information about which IP addresses are operationally used and which link-layer mappings exist. Per-interface parameters are added through augmentation of the interface data model defined in [RFC8343].
数据模型包括每个接口IPv4和IPv6参数的配置，以及IP地址到链路层地址的映射。它还提供了有关操作上使用哪些IP地址以及存在哪些链路层映射的信息。通过扩展[RFC8343]中定义的接口数据模型添加每个接口参数。
This version of the IP data model supports the Network Management Datastore Architecture (NMDA) [RFC8342].
此版本的IP数据模型支持网络管理数据存储体系结构（NMDA）[RFC8342]。
The "ipv4" and "ipv6" subtrees with "config false" data nodes in the "/interfaces-state/interface" subtree are deprecated. All "config false" data nodes are now present in the "ipv4" and "ipv6" subtrees in the "/interfaces/interface" subtree.
不推荐使用“/interfaces state/interface”子树中包含“config false”数据节点的“ipv4”和“ipv6”子树。所有“config false”数据节点现在都存在于“/interfaces/interface”子树中的“ipv4”和“ipv6”子树中。
Servers that do not implement NMDA or that wish to support clients that do not implement NMDA MAY implement the deprecated "ipv4" and "ipv6" subtrees in the "/interfaces-state/interface" subtree.
未实现NMDA或希望支持未实现NMDA的客户端的服务器可以在“/接口状态/接口”子树中实现不推荐使用的“ipv4”和“ipv6”子树。
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.
本文件中的关键词“必须”、“不得”、“必需”、“应”、“不应”、“建议”、“不建议”、“可”和“可选”在所有大写字母出现时（如图所示）应按照BCP 14[RFC2119][RFC8174]所述进行解释。

o client
o 客户

The terminology for describing YANG data models is found in [RFC7950].
描述YANG数据模型的术语见[RFC7950]。
Tree diagrams used in this document follow the notation defined in [RFC8340].
本文档中使用的树形图遵循[RFC8340]中定义的符号。
This document defines the YANG module "ietf-ip", which augments the "interface" lists defined in the "ietf-interfaces" module [RFC8343] with IP-specific data nodes.
本文件定义了YANG模块“ietf ip”，该模块使用ip特定数据节点扩充了“ietf接口”模块[RFC8343]中定义的“接口”列表。
The data model has the following structure for IP data nodes per interface, excluding the deprecated data nodes:
对于每个接口的IP数据节点，数据模型具有以下结构，不包括不推荐使用的数据节点：

The data model defines two containers per interface -- "ipv4" and "ipv6", representing the IPv4 and IPv6 address families. In each container, there is a leaf "enabled" that controls whether or not the address family is enabled on that interface, and a leaf "forwarding" that controls whether or not IP packet forwarding for the address family is enabled on the interface. In each container, there is also a list of addresses and a list of mappings from IP addresses to link-layer addresses.
数据模型为每个接口定义了两个容器——“ipv4”和“ipv6”，表示ipv4和ipv6地址族。在每个容器中，都有一个叶“enabled”，用于控制该接口上是否启用了地址族，还有一个叶“forwarding”，用于控制该接口上是否启用了地址族的IP数据包转发。在每个容器中，还有一个地址列表以及从IP地址到链路层地址的映射列表。
If the device implements the IP-MIB [RFC4293], each entry in the "ipv4/address" and "ipv6/address" lists is mapped to one ipAddressEntry, where the ipAddressIfIndex refers to the "address" entry's interface.
如果设备实现IP-MIB[RFC4293]，则“ipv4/地址”和“ipv6/地址”列表中的每个条目都映射到一个IPAddressEssentry，其中IPAddressLishFindex指的是“地址”条目的接口。
The IP-MIB defines objects to control IPv6 Router Advertisement messages. The corresponding YANG data nodes are defined in [RFC8022].
IP-MIB定义用于控制IPv6路由器播发消息的对象。[RFC8022]中定义了相应的数据节点。
The entries in "ipv4/neighbor" and "ipv6/neighbor" are mapped to ipNetToPhysicalTable.
“ipv4/邻居”和“ipv6/邻居”中的条目映射到ipNetToPhysicalTable。
The following table lists the YANG data nodes with corresponding objects in the IP-MIB.

Reference: RFC 8344
The YANG module specified in this document defines a schema for data that is designed to be accessed via network management protocols such as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer is the secure transport layer, and the mandatory-to-implement secure transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer is HTTPS, and the mandatory-to-implement secure transport is TLS [RFC5246].
本文档中指定的模块为数据定义了一个模式，该模式旨在通过网络管理协议（如NETCONF[RFC6241]或restcconf[RFC8040]）进行访问。最低的NETCONF层是安全传输层，实现安全传输的强制要求是安全Shell（SSH）[RFC6242]。最低的RESTCONF层是HTTPS，实现安全传输的强制层是TLS[RFC5246]。
The NETCONF access control model [RFC8341] provides the means to restrict access for particular NETCONF or RESTCONF users to a preconfigured subset of all available NETCONF or RESTCONF protocol operations and content.
NETCONF访问控制模型[RFC8341]提供了将特定NETCONF或RESTCONF用户的访问限制为所有可用NETCONF或RESTCONF协议操作和内容的预配置子集的方法。
There are a number of data nodes defined in this YANG module that are writable/creatable/deletable (i.e., config true, which is the default). These data nodes may be considered sensitive or vulnerable in some network environments. Write operations (e.g., edit-config) to these data nodes without proper protection can have a negative effect on network operations. These are the subtrees and data nodes and their sensitivity/vulnerability:
此模块中定义了许多可写/可创建/可删除的数据节点（即，默认为config true）。在某些网络环境中，这些数据节点可能被视为敏感或易受攻击。对这些数据节点的写入操作（如编辑配置）如果没有适当的保护，可能会对网络操作产生负面影响。这些是子树和数据节点及其敏感性/漏洞：
ipv4/enabled and ipv6/enabled: These leafs are used to enable or disable IPv4 and IPv6 on a specific interface. By enabling a protocol on an interface, an attacker might be able to create an unsecured path into a node (or through it if routing is also enabled). By disabling a protocol on an interface, an attacker
ipv4/已启用和ipv6/已启用：这些leaf用于在特定接口上启用或禁用ipv4和ipv6。通过在接口上启用协议，攻击者可能能够创建进入节点的不安全路径（如果还启用了路由，则可以通过该路径）。通过禁用接口上的协议，攻击者
might be able to force packets to be routed through some other interface or deny access to some or all of the network via that protocol.
可能能够强制数据包通过其他接口路由，或者拒绝通过该协议访问部分或全部网络。
ipv4/address and ipv6/address: These lists specify the configured IP addresses on an interface. By modifying this information, an attacker can cause a node to either ignore messages destined to it or accept (at least at the IP layer) messages it would otherwise ignore. The use of filtering or security associations may reduce the potential damage in the latter case.
ipv4/地址和ipv6/地址：这些列表指定接口上配置的IP地址。通过修改此信息，攻击者可以使节点忽略发送给它的消息，或者接受（至少在IP层）它本来会忽略的消息。在后一种情况下，使用过滤或安全关联可以减少潜在的损害。
ipv4/forwarding and ipv6/forwarding: These leafs allow a client to enable or disable the forwarding functions on the entity. By disabling the forwarding functions, an attacker would possibly be able to deny service to users. By enabling the forwarding functions, an attacker could open a conduit into an area. This might result in the area providing transit for packets it shouldn't, or it might allow the attacker access to the area, bypassing security safeguards.
ipv4/转发和ipv6/转发：这些叶子允许客户端启用或禁用实体上的转发功能。通过禁用转发功能，攻击者可能会拒绝向用户提供服务。通过启用转发功能，攻击者可以打开进入某个区域的管道。这可能导致该区域为不应该传输的数据包提供传输，或者允许攻击者绕过安全防护措施访问该区域。
ipv6/autoconf: The leafs in this branch control the autoconfiguration of IPv6 addresses and, in particular, whether or not temporary addresses are used. By modifying the corresponding leafs, an attacker might impact the addresses used by a node and -- thus, indirectly -- the privacy of the users using the node.
ipv6/autoconf：此分支中的LEAF控制ipv6地址的自动配置，特别是是否使用临时地址。通过修改相应的leaf，攻击者可能会影响节点使用的地址，从而间接影响使用节点的用户的隐私。
ipv4/mtu and ipv6/mtu: Setting these leafs to very small values can be used to slow down interfaces.
ipv4/mtu和ipv6/mtu：将这些LEAF设置为非常小的值可用于降低接口速度。
