在 Mikrotik RouterOS v7.x 上配置 IPv6## 0. 简介Mikrotik RouterOS 上的 IPv6 配置比 ASUS 上的 Merlin 复杂得多。我们将在本文中配置 IPv6。¶
配置基于 Mikrotik RouterOS 7.6。
1. 配置 DHCPv6 客户端使用以下命令登录 RouterOS 中的终端：```¶
Accept ISP RA, Get IPv6 Address with SLAAC¶
/ipv6 settings set accept-router-advertisements=yes
Configure DHCPv6 client:¶
- Add default route: yes¶
- WAN interface: pppoe-ether1¶
- IPv6 address pool: IPv6 (You can change to whatever you want)¶
- Prefix length for DHCPv6 server's offering cascading routers: 60¶
- Request LAN prefix from ISP¶
/ipv6 dhcp-client add add-default-route=no interface=pppoe-ether1 pool-name=IPv6 pool-prefix-length=60 \ request=prefix
江苏南京移动提供/60前缀，如果前缀长度小于/63，则无法使用DHCPv6。
## 2.添加必要的IPv6防火墙规则```
# Accept DHCPv6 client prefix delegation
/ipv6 firewall filter add action=accept chain=input \
comment="Accept DHCPv6 client prefix delegation" \
dst-port=546 protocol=udp src-address=fe80::/10
如果您使用默认脚本配置了路由器，则此规则是默认的。
3. 为接口分配IPv6地址```¶
/ipv6 address add address=::1 from-pool=IPv6 interface=bridge
## 4.配置DHCPv6-PD服务器```
# Delegate IPv6 addresses from pool `delegation`
# Lease is valid for 1 day
/ipv6 dhcp-server add address-pool=IPv6 \
interface=bridge lease-time=7d name=Home-IPv6
