MSR路由器IS-IS下的基本路由互通功能的配置

 MSR路由器

ISIS路由协议基本功能的配置

 

          关键字: MSR;IPv6;ISIS;路由

一、组网需求

通过运行IS-IS协议实现中间系统到中间系统的域内路由信息交换

        试验设备：RTA（MSR20-21），RTB（MSR20-20）,RTC（MSR30-20）

  适用版本：Version 5.20, Beta 1105

二、组网图

三、配置步骤

   

RTA配置

[RTA]ipv6                           //全局视图下使能Ipv6 [RTA]isis 1 [RTA-isis-1]network-entity 86.0001.0000.0000.0006.00  [RTA-isis-1]ipv6 enable [RTA-isis-1]quit [RTA]interface Ethernet 0/0 [RTA-Ethernet0/0]ipv6 address 2::1/64 [RTA-Ethernet0/0]isis ipv6 enable 1 [RTA-Ethernet0/0]quit

RTB配置

[RTB]ipv6                             //全局视图下使能Ipv6 [RTB] isis 1                            //创建进程号为1的isis实例 [RTB-isis-1]ipv6 enable                  //使能isis的Ipv6功能 [RTB-isis-1]network-entity 86.0001.0000.0000.0005.00 //设置该实例的网络 实体字 [RTB-isis-1]quit [RTB]interface Ethernet 0/0 [RTB-Ethernet0/0]ipv6 address 3::2/64 [RTB-Ethernet0/0]isis ipv6 enable 1         //接口下使能isis 的ipv6功能 [RTB-Ethernet0/0]quit

RTC配置

[RTC]ipv6 [RTC]isis 1 [RTC-isis-1]ipv6 enable [RTC-isis-1]network-entity 86.0001.0000.0000.0007.00 [RTC-isis-1]quit [RTC]interface GigabitEthernet 0/0 [RTC-GigabitEthernet0/0]ipv6 address 2::2/64 [RTC-GigabitEthernet0/0]isis ipv6 enable 100 [RTC-GigabitEthernet0/0]quit [RTC]interface GigabitEthernet 0/1 [RTC-GigabitEthernet0/1]ipv6 address 3::1/64 [RTC-GigabitEthernet0/1]isis ipv6 enable 100 [RTC-GigabitEthernet0/1]quit

 

四、配置关键点

1．              network-entity 值不要重复

2．              在每个接口下都使能ISIS IPv6 enable

五、试验分析

配置完成后通过RTA ping RTB能够ping通,结果显示如下:

<RTA>ping ipv6 3::2

  PING 3::2 : 56  data bytes, press CTRL_C to break

    Reply from 3::2

    bytes=56 Sequence=1 hop limit=63  time = 3 ms

    Reply from 3::2

    bytes=56 Sequence=2 hop limit=63  time = 3 ms

    Reply from 3::2

    bytes=56 Sequence=3 hop limit=63  time = 3 ms

    Reply from 3::2

    bytes=56 Sequence=4 hop limit=63  time = 3 ms

    Reply from 3::2

    bytes=56 Sequence=5 hop limit=63  time = 3 ms

 

  --- 3::2 ping statistics ---

    5 packet(s) transmitted

    5 packet(s) received

    0.00% packet loss

    round-trip min/avg/max = 3/3/3 ms

查看RTB的IPv6路由表，显示有到RTA的ISIS路由，显示如下：
