MSR 26-60 2个串口设置链路聚合并且设置chan双向认证

聚合可以使用mp-group来实现，参考命令如下：

1.5.7  MP配置举例

1. 组网需求

设备Router A和Router B的Serial2/1和Serial2/0分别对应连接。

要求采用MP-group接口实现MP。

2. 组网图

图1-9 MP配置举例组网图

3. 配置步骤

(1)     配置Router A

# 创建MP-group接口，配置相应的IP地址。

<RouterA> system-view

[RouterA] interface mp-group 1

[RouterA-MP-group1] ip address 1.1.1.1 24

# 配置串口Serial2/1。

[RouterA-MP-group1] quit

[RouterA] interface serial 2/1

[RouterA-Serial2/1] link-protocol ppp

[RouterA-Serial2/1] ppp mp mp-group 1

[RouterA-Serial2/1] shutdown

[RouterA-Serial2/1] undo shutdown

[RouterA-Serial2/1] quit

# 配置串口Serial2/0。

[RouterA] interface serial 2/0

[RouterA-Serial2/0] link-protocol ppp

[RouterA-Serial2/0] ppp mp mp-group 1

[RouterA-Serial2/0] shutdown

[RouterA-Serial2/0] undo shutdown

[RouterA-Serial2/0] quit

(2)     配置Router B

# 创建MP-group接口，配置相应的IP地址。

[RouterB] interface mp-group 1

[RouterB-Mp-group1] ip address 1.1.1.2 24

[RouterB-Mp-group1] quit

# 配置串口Serial2/1。

[RouterB] interface serial 2/1

[RouterB-Serial2/1] link-protocol ppp

 [RouterB-Serial2/1] ppp mp mp-group 1

[RouterB-Serial2/1] shutdown

[RouterB-Serial2/1] undo shutdown

[RouterB-Serial2/1] quit

# 配置串口Serial2/0。

[RouterB] interface serial 2/0

[RouterB-Serial2/0] link-protocol ppp

[RouterB-Serial2/0] ppp mp mp-group 1

[RouterB-Serial2/0] shutdown

[RouterB-Serial2/0] undo shutdown

[RouterB-Serial2/0] quit
