※ 引述《Paranoid (Gentoo 萬歲 !!)》之銘言：
: 1. 麻煩您把所有用 route 和 ifconfig 的指令全改為 ip。(我當初也想說沒差，但
: 後來出過靈異現象。)
: 2. 請貼兩台機器的位址表和路由表。(ip -6 addr show 和 ip -6 route show)
: 3. 如果還不行，就應該是 ASCC 那邊沒把您的 3ffe:4001:2118::/48 帶出去。
: ----------------------------------------------------------------------------
: 試試看 .....
: #!/bin/sh
: ip tunnel add ascc mode sit remote 140.109.1.6 local 203.68.42.188 ttl 255
: ip link set ascc up
: ip -6 addr add 2001:288:3b0::9f/127 dev ascc
: ip -6 route add ::/0 dev ascc
: ip -6 route add 3ffe:4001:2118::/64 dev eth1
: # Do forward packets for all interfaces
: echo "1" > /proc/sys/net/ipv6/conf/all/forwarding
我用上述的script執行了。
radvd.conf 新增了AdvRouterAddr on;
--------------------------------------
interface eth1
{
AdvSendAdvert on;
prefix 3ffe:4001:2118::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
結果還是不行~~~~
linux route server 下執行

這是我另一台linux ，用的是chtt的host IPv6 addr
下面是traceroute linux router subnet下的host
# traceroute6 3ffe:4001:2118:0:6e74:a3ff:fef7:83a6
traceroute to 3ffe:4001:2118:0:6e74:a3ff:fef7:83a6 (3ffe:4001:2118:0:6e74:a3ff:f

就這一直重複到~~~~30
會不會是是中研院真的沒幫偶轉~~~~~？
