1 简介

本文档介绍跨设备聚合透明主备方案配置，防火墙设备只做二层透传。

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IRF特性、冗余组特性、链路聚合特性、安全域。

3 使用限制

· F1000&F5000系列防火墙最多支持使用四台设备建立IRF。

· 在F1000&F5000系列防火墙中，只有相同型号的机型之间才能够建立IRF。

· 参与组建IRF的F1000&F5000系列防火墙必须使用相同的软件版本。

4 配置举例

4.1 组网需求

如图1所示，具体应用需求如下：

· FW1050设备做纯二层透传，做IRF；

· 在正常情况下，FW1050主接口被聚合口选中，同时为冗余组的主设备，流量走FW1050主；

· 当主FW1050的链路出现故障时，聚合口内成员口发生切换，冗余组的主备发生联动切换，流量切至备FW1050；

· 当主FW1050的链路故障恢复后，由主FW1050继续承担流量转发功能；

图1 跨设备聚合透明主备方案配置组网图

4.2 配置思路

1、两台F10X0/F50X0组成IRF组网，与下游设备单臂互联，配置为纯二层；

2、互联链路可以是物理链路、子接口、vlan-interface，两台设备各出一个接口组成聚合口，设置聚合组中的最大选中端口数为1，同时设置主设备接口的聚合成员优先级高，此时备机的聚合成员接口down；

3、上下游设备通过活动成员链路上送主设备；

4、F10X0/F50X0上配置链路聚合本地优先，对于本地转发流量优先从本框出，避免横向流量，缺省情况下，聚合负载分担采用本地转发优先，对应命令link-aggregation load-sharing mode local-first；

5、配置冗余组，主备设备track本设备聚合成员接口；

6、上下行设备配置OSPF的情况下，单纯聚合口切换不会导致OSPF路由重新收敛。

4.3 使用版本

本举例是在SecPath F1050 Ess 9310P11版本上进行配置和验证的。

4.4 配置注意事项

· IRF的配置中，做MAD BFD检测的vlan-interface1000要加入安全域trust中，否则MAD BFD检测报文不能通过防火墙，MAD BFD检测失败，无法正常工作；

· 防火墙设备上的二层聚合口及其成员口要带具体的vlan加入到对应的安全域中，否则报文无法通过防火墙；

· 防火墙做IRF，要开启会话同步功能，开启本地IP优先转发功能；

· 防火墙上要开启会话数据统计功能。

4.5 配置步骤

(1) 创建聚合口，配置物理口并加入到聚合口中

# 创建三层路由聚合口，配置IP地址。

<SW5560_1> system-view

# 配置聚合链路成员口最大选中数为1。

[SW5560_1-Route-Aggregation1] link-aggregation selected-port maximum 1

[SW5560_1-Route-Aggregation1] quit

# 配置物理接口。

[SW5560_1] interface GigabitEthernet 1/0/12

[SW5560_1-GigabitEthernet1/0/12] port link-mode route

# 配置高优先级10。

[SW5560_1-GigabitEthernet1/0/12] link-aggregation port-priority 10
