第五十讲神州路由器IPv6隧道的配置

目前IPv6隧道技术有ISATAP隧道、6to4隧道、IPv6 over MPL隧道等。

任务一：配置ISATAP隧道

实验拓扑图如下所示

配置要求：两台路由器ROUTERA和ROUTERB通过IPv4网络连接，要求在两台路由器上分别配置ISATAP隧道，实现两端IPv6主机PC1与PC2互访。

配置步骤：

步骤1：在R1上配置ISATAP隧道

R1_config#interface tunnel 0

R1_config_t0# ipv6 address 1234::/16 eui-64

R1_config_t0# tunnel mode ipv6 ipisatap

R1_config_t0# tunnel source 1.1.1.1

R1_config_t0# exit

R1_config# interface fastEthernet 0/0

R1_config_f0/0#ip address 1.1.1.1 255.255.255.0

验证：

R1_config#show ipv6 int

Tunnel0 is up, line protocol is up

  IPv6 is enabled, link-local address is FE80::5EFE:101:101

 Global unicast address(es):

    1234::5EFE:101:101, subnet is 1234::/16 [EUI]

  Joined group address(es):

    FF02::1

    FF02::1:FF01:101

  MTU is 1460 bytes

  ICMP error messages limited to one every 100 milliseconds

ICMP redirects are enabled

ICMP unreachables are enabled

步骤2：在RouterB上配置ISATAP隧道：

R2_config#interface tunnel 0

R2_config_t0# ipv6 address 1234::/16 eui-64

R2_config_t0# tunnel mode ipv6 ipisatap

R2_config_t0# tunnel source 1.1.1.2

R2_config# interface fastEthernet 0/0

R2_config_f0/0#ip address 1.1.1.2 255.255.255.0

验证：

R2_config#show ipv6 int

Tunnel0 is up, line protocol is up

  IPv6 is enabled, link-local address is FE80::5EFE:101:102

  Global unicast address(es):

  1234::5EFE:101:102, subnet is 1234::/16 [EUI]

  oined group address(es):

    FF02::1

    FF02::1:FF01:102

  MTU is 1460 bytes

  ICMP error messages limited to one every 100 milliseconds

  ICMP redirects are enabled

  ICMP unreachables are enabled

步骤3：测试隧道连通性

R1_config#ping6 1234::5EFE:101:102

PING 1234::5EFE:101:102 (1234::5EFE:101:102): 56 data bytes

!!!!!

--- 1234::5EFE:101:102 ping6 statistics ---

5 packets transmitted, 5 packets received, 0% packet loss

round-trip min/avg/max = 0/2/10ms

RouterB_config#ping6 1234::5EFE:101:101

PING 1234::5EFE:101:101 (1234::5EFE:101:101): 56 data bytes

!!!!!

--- 1234::5EFE:101:101 ping6 statistics ---

5 packets transmitted, 5 packets received, 0% packet loss

round-trip min/avg/max = 0/0/0 ms

步骤4：配置默认路由指向隧道接口

R1_config#ipv6 route ::/0 tunnel 0 fe80::5efe:101:102 

      //此处配置tunnel 0的本地链路地址

R2_config#ipv6 route ::/0 tunnel 0 fe80::5efe:101:101 

      //此处配置tunnel 0的本地链路地址

步骤5：测试主机连通性（路由器G0/4接口IPv6地址及PC机地址配置步骤略）

任务二：配置6to4隧道

实验拓扑图如下所示

配置要求：两台路由器R1和ROUTERB通过IPv4网络连接，要求在两台路由器上分别配置6to 4隧道，实现IPv6主机PC1能够与PC2互访。

配置步骤：

步骤1：在R1上配置IPv6 to IPv4隧道

R1_config#interface tunnel 0

R1_config_t0# ipv6 address 2002:101:101::1/32

R1_config_t0# tunnel mode ipv6ip 6to4

R1_config_t0# tunnel source 1.1.1.1

R1_config_t0# interface fastEthernet 0/0

R1_config_f0/0#ip address 1.1.1.1 255.255.255.0

R1_config_f0/0#exit

步骤2：在RouterB上配置IPv6 to IPv4隧道：

R2_config#interface tunnel 0

R2_config_t0# ipv6 address 2002:101:102::1/32

R2_config_t0# tunnel mode ipv6ip 6to4

R2_config_t0# tunnel source 1.1.1.2

R2_config# interface fastEthernet 0/0

R2_config_f0/0#ip address 1.1.1.2 255.255.255.0

步骤3：测试。在R1的端口G0/4上配置IPv6地址2001::1/64，在R2的端口g0/4上配置IPv6地址2014::1/64。在R1上ping6 R2端口g0/4的地址2014::1/64，或者在RouterB上ping6 R1端口f0/1的地址2001::1/64。在路由器上配置相应的路由。

R1_config# interface GigaEthernet 0/4

R1_config_g0/4#ipv6 address 2001::1/64

R1_config#ipv6 route 2014::/64  2002:101:102::1

R2_config# interface GigaEthernet 0/4

R2_config# ipv6 route2001::/64 2002:101:101::1

步骤4：在R1上验证配置。

R1# ping6 2014::1

PING 2014::1 (2014::1): 56 data bytes

!!!!!

---2014::1 ping6 statistics ---

5 packets transmitted, 5 packets received, 0% packet loss

Round

-trip min/avg/max = 0/0/0 ms

步骤5：在R2上验证配置。

R2#ping6 2001::1

PING 2001::1 (2001::1): 56 data bytes

!!!!!

--- 2001::1 ping6 statistics ---

5 packets transmitted, 5 packets received, 0% packet loss

round-trip min/avg/max = 0/0/0 ms
