NE80/NE40系列路由器IPv6过渡技术NAT-PT功能的配置

NE80/NE40系列路由器IPv6过渡技术

NAT-PT功能的配置

一、组网需求：

RTB为NE40，版本Version 5.30, RELEASE 0228，RTA为双栈路由器；通过配置NAT-PT功能，使得IPv6（用RTA与RTB之间的链路来模拟）网络与IPv4（用RTB与RTC之间的链路来模拟）网络互通。

二、组网图：

         

三、配置步骤：

1.  静态NAT-PT的配置方式

1.1 RTA的配置如下：

<RTA>disp  cur         

#                                                                              

ipv6                                                                    

interface Ethernet2/0/0                                                        

 undo shutdown                                                       

 ipv6 address 1:102::1/64 

#                                                                              

ipv6 route-static 1:2:: 96 1:102::2 

1.2 RTB的配置如下：

<RTB>disp cur

#   

 ipv6                        

 natpt address-group gg1 no-pat 1.1.1.1 1.1.1.10 mask 255.255.255.0 slot 3 

 natpt bound  v4des_v6src  static 1.1.1.1 1:102::1   

 natpt prefix 0001:0002:: address-group  gg1        

interface Ethernet2/0/0                                                        

 undo shutdown                                                                 

 ip address 1.2.4.2 255.255.255.0

 ipv6 address 1:102::2/64                                                      

#                                                                               

interface Ethernet2/0/1                                                        

 undo shutdown                                                                 

 ip address 1.2.3.1 255.255.255.0                                              

#                                                                                                        

 ip route-static 1.1.1.0 255.255.255.0 NULL0                                   

#                                                                               

 ipv6 route-static 1:2:: 96 NULL0 

1.3  RTC的配置为：

#                                                                              

 ipv6 

# 

interface Ethernet4/1/7                                                        

 undo shutdown                                                                  

 ip address 1.2.3.2 255.255.255.0                                              

 rip version 2 multicast

#                                                                                                                                                      

  ipv6 route-static 1:2:: 96 NULL0

2.  动态NAT-PT的配置方式

RTA与RTC的配置保持不变，首先用命令reset natpt session命令删除RTB上已经存在的会话，再在RTB中删除以下配置：

natpt bound v4des_v6src static  1.1.1.1  0001:0102::0001

3. NAT-PT的PAT方式配置

RTA与RTC的配置保持不变，首先用命令reset natpt session命令删除RTB上已经存在的会话，如果将RTB的配置做如下改动：

natpt address-group gg1 pat 1.1.1.1 1.1.1.10 mask 255.255.255.0 slot 3

四、配置关键点：

 对于静态NAT-PT配置完成后会话可以从IPV6或者IPV4侧发起，对于动态NAT-PT会话只能由IPV6侧发起。
