    ip nat enable
interface FastEthernet1/0
    ip nat enable
ip access-list extended PAT
    permit ip 192.168.1.0 0.0.0.255 any
ip nat source list PAT interface FastEthernet1/0 overload
验证：
R6#PING 202.100.2.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 202.100.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 44/78/144 ms
B.两边的IPV6的网络能够互访
----通过配置R1和R4的6to4 tunnel实现
①R1：
interface Tunnel0
    ipv6 unnumbered FastEthernet0/1
    tunnel source FastEthernet1/0
    tunnel mode ipv6ip 6to4
ipv6 route 2002::/16 Tunnel0
②R3：
interface Tunnel0
    ipv6 unnumbered FastEthernet0/1
    tunnel source FastEthernet1/0
    tunnel mode ipv6ip 6to4
ipv6 route 2002::/16 Tunnel0
③验证：
R5#ping 2002:CA64:203::7

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2002:CA64:203::7, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 132/195/384 ms

C.两边的IPV6的网络能否访问native IPV6的网络
----配置R8为IPV6 6to4 Relay实现，并且R1和R3需要将IPV6默认路由指向R8

    tunnel source FastEthernet0/0
    tunnel mode ipv6ip 6to4
----CA64:308为202.100.3.8对应的16位编码

ipv6 route ::/0 2002:CA64:308::1
----IPV6默认路由指向R8的tunnel2002接口地址
③验证：
R5#PING 2001:1::9

Type escape sequence to abort.
