| (本操作需要有基本使用vi的能力) | |
| 1. ssh登入Edgerouter後, sudo vi /etc/ppp/ip-down.d/remove_invalidv6.sh 貼上下列內容 | |
| #!/bin/sh | |
| /sbin/ifconfig switch0 | grep -ivE 'fe80' | grep 'inet6' | awk '{print $3}' | while read -r ipv6addr ; do | |
| echo "Removing $ipv6addr from switch0" >> /tmp/ipv6_remove.log | |
| /sbin/ip -6 addr del $ipv6addr dev switch0 | |
| done | |
| /etc/init.d/radvd restart | |
| 2. 存擋離開後, 輸入: sudo chmod +x /etc/ppp/ip-down.d/remove_invalidv6.sh | |
| 3. 修改此檔, sudo vi /opt/vyatta/sbin/vyatta_gen_radvd.pl , 在243行會看到下列程式碼: | |
| # Write parameters out to config file | |
| print $FD_WR " prefix $prefix {\n"; | |
| foreach my $key (keys %prefix_param_hash) { | |
| print $FD_WR " $key $prefix_param_hash{$key};\n"; | |
| } | |
| print $FD_WR " };\n"; | |
| 在倒數第二行, 新增一行code如下: | |
| # Write parameters out to config file | |
| print $FD_WR " prefix $prefix {\n"; | |
| foreach my $key (keys %prefix_param_hash) { | |
| print $FD_WR " $key $prefix_param_hash{$key};\n"; | |
| } | |
| print $FD_WR " DeprecatePrefix on;\n"; # 新增這一行!! | |
| print $FD_WR " };\n"; | |
| 4. 存擋離開後, 輸入reboot重開機即可. |
