interface Serial3/1
ip address 192.168.3.1 255.255.255.0
R2:
interface Loopback0
ip address 192.168.2.1 255.255.255.0

3、私网起IPV6的EGP（BGP）协议

R4
router bgp 1
bgp router-id 4.4.4.4
neighbor 2002:2201:0102:9::2 remote-as 2
address-family ipv6
neighbor 2002:2201:0102:9::2 activate
network 2002:2201:102:4::/64

R5
router bgp 64512
bgp router-id 5.5.5.5
bgp confederation identifier 2
neighbor 2002:2201:0102:9::1 remote-as 1
neighbor 2002:2201:102:6::1 remote-as 64512

address-family ipv6
neighbor 2002:2201:102:7::1 activate
network 2002:2201:102:8::/64

4、IPV4全网可通（静态及NAT）
R1
ip route 0.0.0.0 0.0.0.0 Serial3/1
R2
ip route 0.0.0.0 0.0.0.0 Serial3/1
ip route 192.168.1.0 255.255.255.0 Serial3/0
ip nat inside source list 1 interface Serial3/1 overload
access-list 1 permit 192.168.0.0 0.0.255.255
interface Serial3/0
ip nat inside
interface Serial3/1
ip nat outside
5、IPV6全网可通（6to4 Tunnel）
R2
interface Tunnel0
ipv6 enable
tunnel source Serial3/1
tunnel mode ipv6ip 6to4
ipv6 route 2002::/16 Tunnel0
R4
interface Tunnel0
ipv6 enable
tunnel source Serial3/0
tunnel mode ipv6ip 6to4
ipv6 route 2002::/16 Tunnel0
R5
ipv6 route ::/0 Serial3/0
R6
ipv6 route ::/0 Serial3/0
R7
ipv6 route ::/0 Serial3/0
R8
ipv6 route ::/0 Serial3/0

四、测试
两个局域网基于6to4 Tunnel可达（R1环回可IPV6 Ping通R8环回）
且R1可访问R3的环回
