求助AC下不同楼栋用同个SSID，不同的vlan网段怎么实现无缝漫游？

您好，请知：

可以参考下AC间漫游的配置举例：

1.9.2  AC间漫游配置举例

1. 组网需求

如图1-2所示，在一个无线网络中，有两台AC，现要求客户端可以在AC内漫游，也可以跨AC漫游。

2. 配置步骤

(1)     配置AC 1

# 创建无线服务模板service，配置SSID为office，并使能服务模版。

<AC1> system-view

[AC1] wlan service-template service

[AC1-wlan-st-test] ssid office

[AC1-wlan-st-test] service-template enable

[AC1-wlan-st-test] quit

# 创建手工AP，名称为ap1，选择AP型号并配置序列号。

[AC1] wlan ap ap1 model WA4320i-ACN

[AC1-wlan-ap-ap1] serial-id 219801A0CNC138011454

# 将服务模板绑定到ap1的Radio 1接口

[AC1-wlan-ap-ap1] radio 1

[AC1-wlan-ap-ap1-radio-1] radio enable

[AC1-wlan-ap-ap1-radio-1] service-template service

[AC1-wlan-ap-ap1-radio-1] quit

[AC1-wlan-ap-ap1] quit

# 创建手工AP，名称为ap2，选择AP型号并配置序列号。

[AC1] wlan ap ap2 model WA4320i-ACN

[AC1-wlan-ap-ap2] serial-id 219801A0CNC138011445

# 将服务模板绑定到ap2的Radio 1接口。

[AC1-wlan-ap-ap2] radio 1

[AC1-wlan-ap-ap2-radio-1] radio enable

[AC1-wlan-ap-ap2-radio-1] service-template service

[AC1-wlan-ap-ap2-radio-1] quit

[AC1-wlan-ap-ap2] quit

# 创建本地漫游组office。

[AC1] wlan mobility group office

# 配置漫游组IACTP隧道IP地址类型为IPv4。

[AC1-wlan-mg-office] tunnel-type ipv4

# 配置AC加入本地漫游组时建立IACTP隧道的源IP地址为10.1.4.22。

[AC1-wlan-mg-office] source ip 10.1.4.22

# 添加本地漫游组内的AC成员，该AC成员用于建立IACTP隧道的源IP地址为10.1.4.23。

[AC1-wlan-mg-office] member ip 10.1.4.23

# 开启漫游组功能。

[AC1-wlan-mg-office] group enable

[AC1-wlan-mg-office] quit

(2)     配置AC 2

# 创建无线无线服务模板service，配置SSID为office，并使能服务模版。

<AC2> system-view

[AC2] wlan service-template service

[AC2-wlan-st-service] ssid office

[AC2-wlan-st-service] service-template enable

[AC2-wlan-st-service] quit

# 创建手工AP，名称为ap3，选择AP型号并配置序列号。

[AC2] wlan ap ap3 model WA4320i-ACN

[AC2-wlan-ap-ap3] serial-id 219801A0CNC138011439

# 将服务模板绑定到ap3的Radio 1接口。

[AC2-wlan-ap-ap3] radio 1

[AC2-wlan-ap-ap3-radio-1] radio enable

[AC2-wlan-ap-ap3-radio-1] service-template service

[AC2-wlan-ap-ap3-radio-1] quit

[AC2-wlan-ap-ap3] quit

# 创建手工AP，名称为ap4，选择AP型号并配置序列号。

[AC2] wlan ap ap4 model WA4320i-ACN

[AC2-wlan-ap-ap4] serial-id 219801A0CNC138011448

# 将服务模板绑定到ap4的Radio 1接口。

[AC2-wlan-ap-ap4] radio 1

[AC2-wlan-ap-ap4-radio-1] radio enable

[AC2-wlan-ap-ap4-radio-1] service-template service

[AC2-wlan-ap-ap4-radio-1] quit

[AC2-wlan-ap-ap4] quit

# 创建本地漫游组office。

[AC2] wlan mobility group office

# 配置漫游组IACTP隧道IP地址类型为IPv4。

[AC2-wlan-mg-office] tunnel-type ipv4

# 配置AC加入本地漫游组时建立IACTP隧道的源IP地址为10.1.4.23。

[AC2-wlan-mg-office] source ip 10.1.4.23

# 添加本地漫游组内的AC成员，该AC成员用于建立IACTP隧道的源IP地址为10.1.4.22。

[AC2-wlan-mg-office] member ip 10.1.4.22

# 开启漫游组功能。

[AC2-wlan-mg-office] group enable

[AC2-wlan-mg-office] quit

3. 验证配置

# 在AC 1查看本地漫游组信息。
