IPV6隧道配置推荐

1. IPV6基本配置注：PC1,PC2均为XP双协议栈系统，但环境中只是用IPV6地址UTM1,UTM2均为linux双协议栈系统，，多张网卡，此环境中只是用IPV6地址PC1的配置如下：（Xp下使用netsh工具配置）netsh interface ipv6 add address 5 2011:2::2netsh interface ipv6 add route ::/0 5 2011:2::1PC2的配置如下：netsh interface ipv6 add address 5 2011:3::2netsh interface ipv6 add route ::/0 5 2011:3::1UTM1的配置如下：[UTM-DX]$ ifconfig eth1 2011:2::1/64 up[UTM-DX]$ ifconfig eth0 2011:1::1/96 up[UTM-DX]$ route -A inet6 add default gw 2011:1::2[UTM-DX]$ echo “1” /proc/sys/net/ipv6/conf/all/forwarding特别注意最后一个命令，开启IPV6转发功能。UTM2的配置如下：[UTM-DX]$ ifconfig eth1 2011:3::1/64 up[UTM-DX]$ ifconfig eth0 2011:1::2/96 up[UTM-DX]$ route -A inet6 add default gw 2011:1::1[UTM-DX]$ echo “1” /proc/sys/net/ipv6/conf/all/forwardingPC1 ping PC2结果如下：C:\Documents and Settings\Aben.Zong ping 2011:3::2Pinging 2011:3::2 with 32 bytes of data:Reply from 2011:3::2: time=6msReply from 2011:3::2: time=1msReply from 2011:3::2: time 1msReply from 2011:3::2: time=1msPing statistics for 2011:3::2: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 6ms, Average = 2ms2. IPV6隧道配置现在修改上面的网络环境,使IPV6的业务网络经过IPV4的网络访问IPV6的业务网络，情况如下图：PC1,PC2的配置和上述配置一致；UTM1的配置如下：[UTM-DX]$ ifconfig eth0 192.168.1.2 up[UTM-DX]$ route add default gw 192.168.1.1UTM2的配置如下：[UTM-DX]$ ifconfig eth0 192.168.2.2 up[UTM-DX]$ route add default gw 192.168.2.1此时，网络状况为PC1与UTM1互通/PC2与UTM2互通/UTM1与UTM2互通，但PC1与PC2不通。UTM1的隧道配置如下：[UTM-DX]$ ip tunnel add sit1 mode sit ttl 64 local 192.168.1.2 remote 192.168.2.2[UTM-DX]$ ifconfig sit1 up[UTM-DX]$ route -A inet6 add ::/0 dev sit1[UTM-DX]$ echo “1” /proc/sys/net/ipv6/conf/all/forwarding特别注意最后一个命令，开启IPV6转发功能，不开起的情况下隧道不通。UTM2的隧道配置如下：[UTM-DX]$ ip tunnel add sit1 mode sit ttl 64 local 192.168.2.2 remote 192.168.1.2[UTM-DX]$ ifconfig sit1 up[UTM-DX]$ route -A inet6 add ::/0 dev sit1[UTM-DX]$ echo “1” /proc/sys/net/ipv6/conf/all/forwarding特别注意最后一个命令，开启IPV6转发功能PC1 ping PC2的结果如下：C:\Documents and Settings\Aben.Zong ping 2011:3::2Pinging 2011:3::2 with 32 bytes of data:Reply from 2011:3::2: time=1msReply from 2011:3::2: time=1msReply from 2011:3::2: time=1msReply from 2011:3::2: time=1msPing statistics for 2011:3::2: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:Minimum = 1ms, Maximum = 1ms, Average = 1ms如果不通，注意查看ip6tables的规则信息。 鸟儿爱美，不仅需要羽毛之美，还需要鸣声婉转之美;
