1. Introduction
1. 介绍

This document introduces a YANG data model [RFC6020] [RFC7950] for the Virtual Router Redundancy Protocol (VRRP) [RFC3768] [RFC5798]. VRRP provides higher resiliency by specifying an election protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN.

本文介绍了虚拟路由器冗余协议(VRRP)[RFC3768][RFC5798]的YANG数据模型[RFC6020][RFC7950]。VRRP通过指定一个选举协议,动态地将虚拟路由器的责任分配给LAN上的一个VRRP路由器,从而提供更高的弹性。

The YANG module specified in this document supports both versions 2 and 3 of VRRP. VRRP version 2 (defined in [RFC3768]) supports IPv4. VRRP version 3 (defined in [RFC5798]) supports both IPv4 and IPv6.

本文件中规定的YANG模块支持VRRP版本2和版本3。VRRP版本2(在[RFC3768]中定义)支持IPv4。VRRP版本3(在[RFC5798]中定义)同时支持IPv4和IPv6。

1.2. Tree Diagrams
1.2. 树形图

A simplified graphical representation of the data model is used in this document. The meaning of the symbols in these diagrams is defined in [RFC8340].

本文件中使用了数据模型的简化图形表示。这些图中符号的含义在[RFC8340]中定义。

1.3. Prefixes in Data Node Names
1.3. 数据节点名称中的前缀

In this document, names of data nodes, actions, and other data model objects are often used without a prefix, as long as it is clear from the context in which YANG module each name is defined. Otherwise, names are prefixed using the standard prefix associated with the corresponding YANG module, as shown in Table 1.

在本文档中,数据节点、动作和其他数据模型对象的名称通常不带前缀,只要定义每个名称的上下文清楚即可。否则,名称将使用与相应模块关联的标准前缀作为前缀,如表1所示。

                 +--------+-----------------+-----------+
                 | Prefix | YANG module     | Reference |
                 +--------+-----------------+-----------+
                 | yang   | ietf-yang-types | [RFC6991] |
                 | inet   | ietf-inet-types | [RFC6991] |
                 | if     | ietf-interfaces | [RFC8343] |
                 | ip     | ietf-ip         | [RFC8344] |
                 +--------+-----------------+-----------+
        
                 +--------+-----------------+-----------+

2. Design of the Data Model
2. 数据模型的设计
2.1. Scope of the Model
2.1. 模型的范围

The model covers VRRP version 2 [RFC3768] and VRRP version 3 [RFC5798]. The model is designed to be implemented on a device where VRRP version 2 or 3 is implemented. With the help of a proper management protocol, the defined model can be used to:

该型号包括VRRP版本2[RFC3768]和VRRP版本3[RFC5798]。该模型设计用于在实施VRRP版本2或3的设备上实施。在适当管理协议的帮助下,定义的模型可用于:

o Configure VRRP version 2 or 3.

o 配置VRRP版本2或3。

o Manage the protocol operational behavior.

o 管理协议操作行为。

o Retrieve the protocol operational status.

o 检索协议操作状态。

o Receive the protocol notifications.

o 接收协议通知。

2.2. Relationships with the Interface Model and IP Model
2.2. 与接口模型和IP模型的关系

This model augments the interface data model "ietf-interfaces" [RFC8343] and the IP management model "ietf-ip" [RFC8344]. The augmentation relationships are shown as follows:

该模型扩充了接口数据模型“ietf接口”[RFC8343]和IP管理模型“ietf IP”[RFC8344]。扩充关系如下所示:

   module: ietf-interfaces
      +--rw interfaces
         +--rw interface* [name]
               ...
            +--rw ip:ipv4!
            |  +--rw ip:address* [ip]
                     ...
            |  +--rw vrrp:vrrp
            |     +--rw vrrp:vrrp-instance* [vrid]
            |        +--rw vrrp:vrid                            uint8
            |        +--rw vrrp:virtual-ipv4-addresses
                           ...
            +--rw ip:ipv6!
               +--rw ip:address* [ip]
                     ...
               +--rw vrrp:vrrp
                  +--rw vrrp:vrrp-instance* [vrid]
                     +--rw vrrp:vrid                            uint8
                     +--rw vrrp:virtual-ipv6-addresses
                           ...
        
   module: ietf-interfaces
      +--rw interfaces
         +--rw interface* [name]
               ...
            +--rw ip:ipv4!
            |  +--rw ip:address* [ip]
                     ...
            |  +--rw vrrp:vrrp
            |     +--rw vrrp:vrrp-instance* [vrid]
            |        +--rw vrrp:vrid                            uint8
            |        +--rw vrrp:virtual-ipv4-addresses
                           ...
            +--rw ip:ipv6!
               +--rw ip:address* [ip]
                     ...
               +--rw vrrp:vrrp
                  +--rw vrrp:vrrp-instance* [vrid]
                     +--rw vrrp:vrid                            uint8
                     +--rw vrrp:virtual-ipv6-addresses
                           ...
        

In the above figure, a tree node without a prefix is from the model "ietf-interfaces". A tree node with prefix "ip:" is from the model "ietf-ip". A tree node with prefix "vrrp:" is from the VRRP model specified in this document.

在上图中,没有前缀的树节点来自模型“ietf接口”。前缀为“ip:”的树节点来自模型“ietf ip”。前缀为“vrrp:”的树节点来自本文档中指定的vrrp模型。

The "vrrp" container contains a list of vrrp-instance nodes, which are instantiated under an interface for a specified address family (IPv4 or IPv6).

“vrrp”容器包含vrrp实例节点列表,这些节点在指定地址系列(IPv4或IPv6)的接口下实例化。

Each vrrp-instance node represents a VRRP router state machine, as described in Section 6.4 of [RFC5798], providing the configuration and state information for the election process of a virtual router. The IP addresses on the augmented interface are the real addresses through which the VRRP router operates. The IPv4 or IPv6 address or addresses associated with a virtual router (described in Section 1 of [RFC5798]) are modeled as a list of IPv4 or IPv6 addresses under the vrrp-instance.

每个vrrp实例节点代表一个vrrp路由器状态机,如[RFC5798]第6.4节所述,为虚拟路由器的选择过程提供配置和状态信息。增强接口上的IP地址是VRRP路由器操作的真实地址。与虚拟路由器(如[RFC5798]第1节所述)关联的IPv4或IPv6地址建模为vrrp实例下的IPv4或IPv6地址列表。

2.3. Protocol Configuration

This model conforms to the Network Management Datastore Architecture (NMDA) [RFC8342]. The operational state data is combined with the associated configuration data in the same hierarchy [YANG-Guidelines]. When protocol states are retrieved from the NMDA operational state datastore, the returned states cover all "config true" (rw) and "config false" (ro) nodes defined in the schema.

该模型符合网络管理数据存储体系结构(NMDA)[RFC8342]。操作状态数据与同一层次结构中的相关配置数据相结合[1]。当从NMDA操作状态数据存储中检索到协议状态时,返回的状态覆盖模式中定义的所有“config true”(rw)和“config false”(ro)节点。

The model allows the retrieval of protocol states at the following levels:

该模型允许在以下级别检索协议状态:

o VRRP instance (version 2 or 3), representing a VRRP router.

o VRRP实例(版本2或3),表示VRRP路由器。

o Virtual IPv4 or IPv6 address associated with a virtual router.

o 与虚拟路由器关联的虚拟IPv4或IPv6地址。

o Tracking interface, to detect interface connectivity failures.

o 跟踪接口,以检测接口连接故障。

o Tracking network, to detect network connectivity failures.

o 跟踪网络,以检测网络连接故障。

o Global states and statistics summarizing all instances.

o 汇总所有实例的全局状态和统计信息。

2.5. Notifications
2.5. 通知

This model defines the following VRRP-specific notifications:

此模型定义了以下特定于VRRP的通知:

   notifications:
      +---n vrrp-new-master-event
      |  +--ro master-ip-address    inet:ip-address
      |  +--ro new-master-reason    new-master-reason-type
      +---n vrrp-protocol-error-event
      |  +--ro protocol-error-reason    identityref
      +---n vrrp-virtual-router-error-event
         +--ro interface                      if:interface-ref

         |  |     +--ro vrid    leafref
         |  +--:(ipv6)
         |     +--ro ipv6
         |        +--ro vrid    leafref
         +--ro virtual-router-error-reason    identityref
        
   notifications:
      +---n vrrp-new-master-event
      |  +--ro master-ip-address    inet:ip-address
      |  +--ro new-master-reason    new-master-reason-type
      +---n vrrp-protocol-error-event
      |  +--ro protocol-error-reason    identityref
      +---n vrrp-virtual-router-error-event
         +--ro interface                      if:interface-ref
         +--ro (ip-version)
         |  +--:(ipv4)
         |  |  +--ro ipv4
         |  |     +--ro vrid    leafref
         |  +--:(ipv6)
         |     +--ro ipv6
         |        +--ro vrid    leafref
         +--ro virtual-router-error-reason    identityref
        

Each notification type is used to indicate a type of VRRP state change or error occurrence:

每种通知类型用于指示VRRP状态更改或错误发生的类型:

vrrp-new-master-event VRRP new master event, indicating that a new master has been elected.

vrrp新主机事件vrrp新主机事件,表示已选择新主机。

vrrp-protocol-error-event VRRP protocol error event for a message that fails to reach a VRRP instance to be processed.

vrrp协议错误事件无法到达要处理的vrrp实例的消息的vrrp协议错误事件。

vrrp-virtual-router-error-event VRRP virtual router error event for a message processed on a VRRP instance.

vrrp虚拟路由器错误事件在vrrp实例上处理的消息的vrrp虚拟路由器错误事件。

In addition to the notifications specified above, the mechanisms defined in [Subscribed-Notifications] and [YANG-Push] can be used for other general notifications. These mechanisms currently allow the user to:

除了上面指定的通知外,[Subscribed notifications]和[YANG Push]中定义的机制还可用于其他常规通知。这些机制目前允许用户:

o Subscribe notifications on a per-client basis.

o 按每个客户端订阅通知。

o Specify subtree filters or XML Path Language (XPath) filters so that only contents of interest will be sent.

o 指定子树筛选器或XML路径语言(XPath)筛选器,以便只发送感兴趣的内容。

o Specify either periodic or on-demand notifications.

o 指定定期或按需通知。

6. Security Considerations
6. 安全考虑

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:

   /if:interfaces/if:interface/ip:ipv4/vrrp:vrrp/vrrp:vrrp-instance
        
   /if:interfaces/if:interface/ip:ipv4/vrrp:vrrp/vrrp:vrrp-instance
        
   /if:interfaces/if:interface/ip:ipv6/vrrp:vrrp/vrrp:vrrp-instance
        
   /if:interfaces/if:interface/ip:ipv6/vrrp:vrrp/vrrp:vrrp-instance
        

Unauthorized access to any data node of these subtrees can adversely affect the routing subsystem of both the local device and the network. This may lead to network malfunctions, delivery of packets to inappropriate destinations, and other problems.

未经授权访问这些子树的任何数据节点都可能对本地设备和网络的路由子系统产生不利影响。这可能导致网络故障、将数据包传送到不适当的目的地以及其他问题。

Some of the readable data nodes in this YANG module may be considered sensitive or vulnerable in some network environments. It is thus important to control read access (e.g., via get, get-config, or notification) to these data nodes. These are the subtrees and data nodes and their sensitivity/vulnerability:

在某些网络环境中,此模块中的某些可读数据节点可能被视为敏感或易受攻击。因此,控制对这些数据节点的读取访问(例如,通过get、get config或通知)非常重要。这些是子树和数据节点及其敏感性/漏洞:

/ietf-vrrp:vrrp

/ietf vrrp:vrrp

   /if:interfaces/if:interface/ip:ipv4/vrrp:vrrp/vrrp:vrrp-instance
        
   /if:interfaces/if:interface/ip:ipv4/vrrp:vrrp/vrrp:vrrp-instance
        
   /if:interfaces/if:interface/ip:ipv6/vrrp:vrrp/vrrp:vrrp-instance
        
   /if:interfaces/if:interface/ip:ipv6/vrrp:vrrp/vrrp:vrrp-instance
        

Unauthorized access to any data node of these subtrees can disclose the operational state information of VRRP on this device.

未经授权访问这些子树的任何数据节点可能会泄露此设备上VRRP的操作状态信息。
