# 要求: #

## 如图所示，客户网络所有路由器路由协议要求启用IS-IS，使全网路由可达。 ##

## 全部IS-IS进程号统一为100 ##

## R1引入直连链路，要求R5访问Area 49.0001走最优路径。 ##

## 根据上述描述，进行正确配置，使网络路由达到客户需求。 ##

## 拓扑结构 ##

    [AR2-GigabitEthernet0/0/1]ip address 4.4.4.1 24

**AR3**

<Huawei>sys
    [Huaweisys AR3	
    [AR3]interface g0/0/0
    [AR3-GigabitEthernet0/0/0]ip add 1.1.1.2 24
    [AR3-GigabitEthernet0/0/0]interface g0/0/1
    [AR3-GigabitEthernet0/0/1]ip add 2.2.2.1 24

**AR4**

<Huawei>sys
    [huawei]sys AR4
    [AR4]interface g0/0/0
    [AR4-GigabitEthernet0/0/0]ip add 1.1.1.3 24
    [AR4-GigabitEthernet0/0/0]qu
    [AR4]interface ser4/0/0
    [AR4-Serial4/0/0]ip add 3.3.3.1 24

**AR5**

<Huawei>sys
    [Huawei]sys AR5
    [AR5]interface g0/0/0
    [AR5-GigabitEthernet0/0/0]ip address 1.1.1.1 24

### 2、配置ISIS ###

**AR1**

[AR1]isis 100    //启用isis进程
    [AR1-isis-100]network-entity 49.0001.0000.0000.0001.00 //
    [AR1-isis-100]is-level level-2 //指定路由器isis角色为骨干路由器

**AR2**

[AR2]isis 100
    [AR2-isis-100]network-entity 49.0001.0000.0000.0002.00
    [AR2-isis-100]is-level level-2

**AR3**

[AR3]isis 100
    [Huawei-isis-100]network-entity 49.0002.0000.0000.0003.00

** AR4**

[AR4]isis 100
    [AR4-isis-100]network-entity 49.0002.0000.0000.0004.00

**AR5**

[AR5]isis 100
    [AR5-isis-100]network-entity 49.0002.0000.0000.0005.00
    [AR5-isis-100]is-level level-1

### 3、接口启用ISIS    isis enable 100 ###

**AR1**

[AR1]inte g0/0/0
    [AR1-GigabitEthernet0/0/0]isis enable 100

**AR2**

[AR2]inte g0/0/0
    [AR2-GigabitEthernet0/0/0]isis 100
    [AR2-GigabitEthernet0/0/0]interface g0/0/1
    [AR2-GigabitEthernet0/0/1]isis enable 100
    [AR2-GigabitEthernet0/0/1]inte s4/0/0
    [AR2-Serial4/0/0]isis 100

**AR3**

[AR3]interface g0/0/0	
    [AR3-GigabitEthernet0/0/0]isis enable 100
    [AR3-GigabitEthernet0/0/0]interface g0/0/1
    [AR3-GigabitEthernet0/0/1]isis enable 100

**AR4**

[AR4]inter g0/0/0
    [AR4-GigabitEthernet0/0/0]isis enable 100
    [AR4-GigabitEthernet0/0/0]inter s4/0/0
    [AR4-Serial4/0/0]isis enable 100

**AR5**

[AR5]interface g0/0/0
    [AR5-GigabitEthernet0/0/0]isis enable 100

### 4、AR1 ISIS引入直连回环口 ###

[AR1]isis 100
    [AR1-isis-100]import-route direct

### 5、AR3/AR4 把 level-2 路由引入 level-1 （路由渗透） ###

**AR3 **

[AR3]isis 100
    [AR3-isis-100]import-route isis level-2 into level-1

**AR4**

[AR4]isis 100
    [AR4-isis-100]import-route isis level-2 into level-1
