nettopaz中继线无法使用如何开通

NPMA帖中继网络配置

一、 网络拓扑图

二、 需求：利用帧中继交换机通过串口连路实现全网互通，就是点到点的NPMA网络互通

三、 具体步骤

给每台路由器添加串口模块（模拟真实机）

给每台路由器配置IP地址，并选择帧中继协议。

AR6:

[Huawei]interface s4/0/0

[Huawei-Serial4/0/0]ip add 123.0.0.1 24

[Huawei-Serial4/0/0]link-protocol fr

AR7:

[Huawei]interface s4/0/0

[Huawei-Serial4/0/0]ip add 123.0.0.2 24

[Huawei-Serial4/0/0]link-protocol fr

AR8:

[Huawei]interface s4/0/0

[Huawei-Serial4/0/0]ip add 123.0.0.3 24

[Huawei-Serial4/0/0]link-protocol fr

配置帧中继交换机映射，也就是VC虚拟链路，交换机会在内部进行链路的转换

4.手动配置路由器帖中继映射（自动会映射）

AR6:

[Huawei]interface s4/0/0

[Huawei-Serial4/0/0]fr map ip 123.0.0.2 102 broadcast t //（加broadcast 支持组播和广播）

[Huawei-Serial4/0/0]fr map ip 123.0.0.2 103 broadcast

[Huawei-Serial4/0/0]undo fr inarp //（IE考试需要关掉inarp特性）

[Huawei-Serial4/0/0]display fr map-info //查看映射信息，状态必须是ACTIVVE

Map Statistics for interface Serial4/0/0 (DTE)

DLCI = 102, IP 123.0.0.2, Serial4/0/0

create time = 2019/09/16 22:29:50, status = ACTIVE

encapsulation = ietf, vlink = 3, broadcast

DLCI = 103, IP 123.0.0.3, Serial4/0/0

create time = 2019/09/16 22:31:07, status = ACTIVE

encapsulation = ietf, vlink = 4, broadcast

AR7:

[Huawei]interface s4/0/0

[Huawei-Serial4/0/0]fr map ip 123.0.0.1 201 broadcast

[Huawei-Serial4/0/0]fr map ip 123.0.0.3 203 broadcast //（加broadcast 支持组播和广播）

[Huawei-Serial4/0/0]undo fr inarp //（IE考试需要关掉inarp特性）

[Huawei-Serial4/0/0]display fr map-info //查看映射信息，状态必须是ACTIVVE

Map Statistics for interface Serial4/0/0 (DTE)

DLCI = 102, IP 123.0.0.2, Serial4/0/0

DLCI = 103, IP 123.0.0.3, Serial4/0/0

create time = 2019/09/16 22:31:07, status = ACTIVE

encapsulation = ietf, vlink = 4, broadcast

AR8:

[Huawei]interface s4/0/0

[Huawei-Serial4/0/0]fr map ip 123.0.0.2 301 broadcast //（加broadcast 支持组播和广播）

[Huawei-Serial4/0/0]fr map ip 123.0.0.2 302 broadcast

[Huawei-Serial4/0/0]undo fr inarp //（IE考试需要关掉inarp特性）

[Huawei-Serial4/0/0]display fr map-info //查看映射信息，状态必须是ACTIVVE
