H3C S5830V2&S5820V2 IPv6 over IPv4 GRE隧道典型配置

各位好~   

    我严格按照配置实例配置，使用相同的组网，设备顺序不一样，发现pcA ping ipv6 不通pcB，到各自ipv6的网关都通，设备1到设备3的ipv6的网关2001::1是通的，设备3到设备1001::1也是通的，求助。

设备1配置：# service-loopback group 1 type tunnel # vlan 10 # vlan 20 # interface Vlan-interface10 5 ip address 192.13.2.2 255.255.255.0 # interface Vlan-interface20 ipv6 address 1001::1/64 # interface Ten-GigabitEthernet1/0/1 port link-mode bridge port access vlan 20 # interface Ten-GigabitEthernet1/0/2 port link-mode bridge port access vlan 10 # interface Ten-GigabitEthernet1/0/3 port link-mode bridge port service-loopback group 1 # interface Tunnel0 mode gre ipv6 address 3001::1/64 source 192.13.2.2 destination 131.108.5.2 # ip route-static 131.108.5.2 255.255.255.0 192.13.2.1 # ipv6 route-static 2001:: 64 Tunnel 0

设备2配置：vlan 10 to 11 # interface Vlan-interface10 ip address 192.13.2.1 255.255.255.0 # interface Vlan-interface11 ip address 131.108.5.1 255.255.255.0 # interface Ten-GigabitEthernet1/0/1 port link-mode bridge port access vlan 10 # interface Ten-GigabitEthernet1/0/2 port link-mode bridge port access vlan 11 #
 

设备三配置：service-loopback group 1 type tunnel # vlan 11 # vlan 20 # interface Vlan-interface11 ip address 131.108.5.2 255.255.255.0 # interface Vlan-interface20 ipv6 address 2001::1/64 # interface Ten-GigabitEthernet1/0/1 port link-mode bridge port access vlan 20 # interface Ten-GigabitEthernet1/0/2 port link-mode bridge port access vlan 11 # 6 interface Ten-GigabitEthernet1/0/3 port link-mode bridge port service-loopback group 1 # interface Tunnel0 mode gre ipv6 address 3001::2/64 source 131.108.5.2 destination 192.13.2.2 # ip route-static 192.13.2.2 255.255.255.0 131.108.5.1 # ipv6 route-static 1001:: 64 Tunnel 0
