您好，请知：

以下是配置案例，请参考：

H3C vBRAS系列虚拟宽带远程接入服务器CGN NAT典型配置举例

3  配置举例

3.1  组网需求

如图1所示：

·     Switch与堆叠的vBRAS建立VXLAN隧道，将PPPoE/IPoE报文上送到vBRAS侧。

·     vBRAS上配置NAT业务联动（通过在认证ISP域中指定具体的用户地址类型），用户通过AAA认证并分配得到私网地址之后，NAT网关会立即为该用户分配公网地址以及端口块，并将用户的私网IP地址、分配的公网地址及该端口块的映射关系通知给vBRAS（如果NAT网关上可分配的公网资源已耗尽，vBRAS会强制用户下线，也不会对用户进行计费）。

·     vBRAS记录该地址映射关系，并将这个映射关系上报给AAA服务器。之后，该用户访问外部网络时直接使用NAT网关已经分配的公网地址和端口块。

·     通过此联动功能，AAA服务器能够获得并统一维护所有用户的地址映射关系，提供更便捷的用户溯源服务。

图1 CGN NAT典型配置举例组网图

 

3.2  配置思路

vBRAS设备需要支持PPPoE/IPoE与CGN NAT联动，其中交换机为用户接入相连的设备，负责报文转发与流量控制等，vBRAS为PPPoE/IPoE控制模块设备，负责用户识别与发起认证请求、身份认证、NAT地址转换和接入控制。在交换机和vBRAS之间建立VXLAN隧道，VXLAN隧道提供交换机与vBRAS间的协议报文通道和流量转发。

3.3  使用版本

本举例是在vBRAS1000_H3C-CMW710-E1116-X64版本上进行配置和验证的。

3.4  配置注意事项

·     配置备份组功能通过指定备份组，设备会将需要进行动态NAT（包括动态地址转换和NAT端口块动态映射）或NAT端口块静态映射的流量引到指定的备份组处理，提高了NAT业务处理的性能。

·     目前，支持vBRAS联动功能的用户地址类型包括私网IP地址（private-ipv4）、私网双栈地址（private-ds）和轻量级双栈地址（ds-lite）。

·     用户上线后，无法更改NAT端口块配置。只有在所有用户下线后，才能更改NAT端口块配置。

·     在IRF组网且NAT与BRAS联动的场景中，建议同时开启NAT端口块备份功能和会话业务热备份功能（通过session synchronization enable命令），以保证主备倒换时尽可能缩短流量中断的时间。

1  简介

本文档介绍运营商级网络地址转换的典型配置举例。CGN（Carrier Grade NAT，运营商级网络地址转换），也称LSN（Large-scale NAT，大规模网络地址转换）。传统NAT多部署在CPE（Customer Premises Equipment，用户侧设备）上，实现少量用户地址的转换。而CGN部署在运营商网络中，通过将承担CGN功能的单板插在其他功能（如BRAS）的设备上，实现大量用户的地址转换，在支持并发用户数、性能、溯源等方面有很大提升。

2  配置前提

·     本文档不严格与具体软、硬件版本对应，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。

·     本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。

·     本文档假设您已了解VXLAN、NAT、PPPoE/IPoE等特性。

3  配置举例

3.1  组网需求

如图1所示：

·     Switch与堆叠的vBRAS建立VXLAN隧道，将PPPoE/IPoE报文上送到vBRAS侧。

·     vBRAS上配置NAT业务联动（通过在认证ISP域中指定具体的用户地址类型），用户通过AAA认证并分配得到私网地址之后，NAT网关会立即为该用户分配公网地址以及端口块，并将用户的私网IP地址、分配的公网地址及该端口块的映射关系通知给vBRAS（如果NAT网关上可分配的公网资源已耗尽，vBRAS会强制用户下线，也不会对用户进行计费）。

·     vBRAS记录该地址映射关系，并将这个映射关系上报给AAA服务器。之后，该用户访问外部网络时直接使用NAT网关已经分配的公网地址和端口块。

·     通过此联动功能，AAA服务器能够获得并统一维护所有用户的地址映射关系，提供更便捷的用户溯源服务。

图1 CGN NAT典型配置举例组网图

 

3.2  配置思路

vBRAS设备需要支持PPPoE/IPoE与CGN NAT联动，其中交换机为用户接入相连的设备，负责报文转发与流量控制等，vBRAS为PPPoE/IPoE控制模块设备，负责用户识别与发起认证请求、身份认证、NAT地址转换和接入控制。在交换机和vBRAS之间建立VXLAN隧道，VXLAN隧道提供交换机与vBRAS间的协议报文通道和流量转发。

3.3  使用版本

本举例是在vBRAS1000_H3C-CMW710-E1116-X64版本上进行配置和验证的。

3.4  配置注意事项

·     配置备份组功能通过指定备份组，设备会将需要进行动态NAT（包括动态地址转换和NAT端口块动态映射）或NAT端口块静态映射的流量引到指定的备份组处理，提高了NAT业务处理的性能。

·     目前，支持vBRAS联动功能的用户地址类型包括私网IP地址（private-ipv4）、私网双栈地址（private-ds）和轻量级双栈地址（ds-lite）。

·     用户上线后，无法更改NAT端口块配置。只有在所有用户下线后，才能更改NAT端口块配置。

·     在IRF组网且NAT与BRAS联动的场景中，建议同时开启NAT端口块备份功能和会话业务热备份功能（通过session synchronization enable命令），以保证主备倒换时尽可能缩短流量中断的时间。

1  简介

本文档介绍运营商级网络地址转换的典型配置举例。CGN（Carrier Grade NAT，运营商级网络地址转换），也称LSN（Large-scale NAT，大规模网络地址转换）。传统NAT多部署在CPE（Customer Premises Equipment，用户侧设备）上，实现少量用户地址的转换。而CGN部署在运营商网络中，通过将承担CGN功能的单板插在其他功能（如BRAS）的设备上，实现大量用户的地址转换，在支持并发用户数、性能、溯源等方面有很大提升。

2  配置前提

·     本文档不严格与具体软、硬件版本对应，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。

·     本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。

·     本文档假设您已了解VXLAN、NAT、PPPoE/IPoE等特性。

3  配置举例

3.1  组网需求

如图1所示：

·     Switch与堆叠的vBRAS建立VXLAN隧道，将PPPoE/IPoE报文上送到vBRAS侧。

·     vBRAS上配置NAT业务联动（通过在认证ISP域中指定具体的用户地址类型），用户通过AAA认证并分配得到私网地址之后，NAT网关会立即为该用户分配公网地址以及端口块，并将用户的私网IP地址、分配的公网地址及该端口块的映射关系通知给vBRAS（如果NAT网关上可分配的公网资源已耗尽，vBRAS会强制用户下线，也不会对用户进行计费）。

·     vBRAS记录该地址映射关系，并将这个映射关系上报给AAA服务器。之后，该用户访问外部网络时直接使用NAT网关已经分配的公网地址和端口块。

·     通过此联动功能，AAA服务器能够获得并统一维护所有用户的地址映射关系，提供更便捷的用户溯源服务。

图1 CGN NAT典型配置举例组网图

 

3.2  配置思路

vBRAS设备需要支持PPPoE/IPoE与CGN NAT联动，其中交换机为用户接入相连的设备，负责报文转发与流量控制等，vBRAS为PPPoE/IPoE控制模块设备，负责用户识别与发起认证请求、身份认证、NAT地址转换和接入控制。在交换机和vBRAS之间建立VXLAN隧道，VXLAN隧道提供交换机与vBRAS间的协议报文通道和流量转发。

3.3  使用版本

本举例是在vBRAS1000_H3C-CMW710-E1116-X64版本上进行配置和验证的。

3.4  配置注意事项

·     配置备份组功能通过指定备份组，设备会将需要进行动态NAT（包括动态地址转换和NAT端口块动态映射）或NAT端口块静态映射的流量引到指定的备份组处理，提高了NAT业务处理的性能。

·     目前，支持vBRAS联动功能的用户地址类型包括私网IP地址（private-ipv4）、私网双栈地址（private-ds）和轻量级双栈地址（ds-lite）。

·     用户上线后，无法更改NAT端口块配置。只有在所有用户下线后，才能更改NAT端口块配置。

·     在IRF组网且NAT与BRAS联动的场景中，建议同时开启NAT端口块备份功能和会话业务热备份功能（通过session synchronization enable命令），以保证主备倒换时尽可能缩短流量中断的时间。
