我的AS號和IP都已經沾灰了，再不用就要徹底忘了。
在你開始之前，請確定你的ISP 为你分配了一个公网 IPv4, 並且你拥有 ASN 和一个至少为 / 48 的 ipv6 block
開始之前的一點PY交易
準備Py之前，請確定如下內容(來自HE),不然你去PY也沒有意義
Through this interface you can request a static, IPv6 BGP tunnel that will receive full transit routes from AS6939 and be able to announce your RIR allocated IPv6 space. To minimize any issues or delays in turnup please note the following: Your ASN must be allocated from a RIR. (Public ASNs only) We must be able to validate that this is your ASN/address space (SWIP entries or a LoA will do) We will prefix-filter your BGP session. If you are adding new announcements, please let us know via an email to ipv6@he.net. We do not filter traffic. However, we do reserve the right to filter at our sole discretion as needed. If this is your first tunnel for this ASN, you should receive a message to your account’s email address. Please follow the instructions in the email to complete the verification process. During this period the tunnel and BGP session will be unavailable. If you have not heard from us within 48 hours then please email ipv6@he.net. 地址：tunnelbroker.net
然後你就可以去註冊一個帳號，之後创建一个 BGP 隧道，選擇最近的节点，填寫你的ASN以及IP段 最後你需要一封Authorize Letter（LoA） 提交24小時左右PY交易就會成功
創建隧道
訪問tunnelbroker
Tunnel - Example Config - Linux net-tools
配置大概張這個樣子
ifconfig sit0 inet6 tunnel ::0.0.0.0
ifconfig sit1 up
ifconfig sit1 inet6 add ::::/64
route -A inet6 add ::/0 dev sit1
廣播
安裝bird6
yum install bird6 -y
或者
apt -y install bird
編輯 bird6.conf
注意：
- router id請寫本機ip
- local as是你的asn
- source add是HE給你的client ip
- neighbor是 HE分配的 server ip,6939 为 he 的 asn 号码
router id 本機ip;
protocol bgp he
{
local as 208884;
source address Client_ip;
import none;
export all;
graceful restart on;
multihop 2;
neighbor server_ip as 6939;
}
protocol static
{
route 你的ip段 via cleint_ip;
}
protocol device
{
scan time 5;
}
之後保存推出，重載bird配置，或者重啓bird即可
最後birdc6 show proto all
顯示Established即可

宣告
創建虛擬網卡並分配ip
ip link add dev dummy1 type dummy
ip link set dummy1 up
ip addr add dev dummy1 2001:2333:2333::1/128
編輯bird6.conf加入
protocol direct
{
interface "dummy*";
import all;
}
之後
systemctl restart bird6
這樣 bird 將查詢所有 dummy 开头的网卡的 ip 并宣告这些 ip
birdc6 show route 查看
