为什么 ipv6 链接本地地址条目在邻居表中显示为“路由器”(ipv6链路本地地址ping不通)

如何解决为什么 ipv6 链接本地地址条目在邻居表中显示为“路由器”

我的问题是当邻居表条目具有“路由器”字段时这意味着什么。

ping 之前:

fe80::d635:1dff:fe0a:3e58 Failed

ping 后:

root@host-renga# ip neigh show dev brlan0
192.168.0.226 lladdr d4:35:1d:0a:3e:58 STALE
fe80::d635:1dff:fe0a:3e58 lladdr d4:35:1d:0a:3e:58 router STALE

这是否意味着 MAC 地址为 ''d4:35:1d:0a:3e:58'' 的主机是路由器/默认网关设备。 我参考了 ip-neighbor 手册页,但没有得到确切的含义。

任何信息都可以帮助我理解邻居表。

Pay attention to  this(   listen       [::]:80 ipv6only=on; )

Create dns configuration on Windows Server 2008 such as :

www.test.com and 2001::1008 and www.test.com 192.168.12.13

then on the windows teminal you can type :

nslookup www.test.com  192.168.12.13

, which means that dns server can resolve the domain name www.test.com to an IPv6 address that both of them can communicate.

Cisco 交换机/路由器 ssh 配置

Cisco 交换机/路由器 ssh 配置

一准备工作:

1.开启交换机/路由器

2.连击Console控制线,到控制电脑

3.打开com口控制软件(支持ssh协议)

二配置工作:

1.进入特权模式

Cisco> enable

2.输入密码

Password:

3.进入全局配置模式

Cisco# conf t

4.进入接口

(1)路由器输入

Cisco(config)#int GigabitEthernet 0/1 

 (2)交换机输入

Cisco(config)#int Vlan 1

5.根据需要配置IP

Cisco (config-if)#ip add x.x.x.x x.x.x.x

6.打开接口

Cisco (config-if)#no shutdown

7.可查看以上配置(可跳过,需要时查看)

Cisco (config-if)#do sh ip int br

查看当前接口配置

8.退出接口

Cisco (config-if)#exi

9.设置域名

Cisco (config)#ip domain-name cisco.com   

为交换机/路由器配置一个域名,也可以认为该交换机/路由器属于这个域

10.配置SSH加密方式

Cisco (config)#crypto key generate rsa 

生成一个为rsa算法的密钥

The name for the keys will be: R1.cisco.com

Choose the size of the key modulus in the range of 360 to 2048 for your

  General Purpose Keys. Choosing a key modulus greater than 512 may take

  a few minutes.

How many bits in the modulus [512]: 1024 ----------设置密钥为1024位

% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]

*Mar  1 00:59:17.179: %SSH-5-ENABLED: SSH 1.99 has been enabled

 

PS:在Cisoc中rsa支持360-2048位密钥,该算法的原理是:主机将自己的公用密钥分发给相关的客户机,客户机在访问主机时则使用该主机的公开密钥来加密数据,主机则使用自己的私有的密钥来解密数据,从而实现主机密钥认证,确定客户机的可靠身份。

11.配置虚拟终端

Cisco (config)#line vty 0 5

12.使用本地数据库

Cisco (config-line)#login local   

13.配置远程登录方式

Cisco (config-line)#transport input ssh  

可先用Cisco (config-line)#transport input none     ----------关闭VTY其他的远程登录协议

14.允许远程登录(非常重要)

Cisco (config-line)# access-class 1 in

15.退出虚拟终端

Cisco (config-line)#exi

16.创建用户名和密码

Cisco (config)#username admin password admin

17.设置特权密码(可不设)

Cisco (config)#enable secret cisco 

18.加入AAA认证

Cisco (config)# aaa new-model

19.配置ssh超时时间

Cisco (config)#ip ssh time-out 120

20.设置ssh版本

Cisco (config)#ip ssh version 2  

配置完成
