# OCI infrastructure recovery

||||
# OCI 云上基础设施
|
||||
|
||||
The original Terraform source is currently unavailable. The likely authoritative
|
||||
state remains in OCI Object Storage. Reconstruct configuration here only after
|
||||
taking an encrypted independent state backup.
|
||||
`terraform/` 是独立 Terraform 根模块，从 OCI Object Storage 中的现有 state 恢复。
|
||||
Terraform 管理云 API 资源；实例内的软件、Kubernetes 和操作系统配置不在该 state 中。
|
||||
|
||||
Safety requirements:
|
||||
## 资源与来源
|
||||
|
||||
- preserve the existing state lineage and serial;
|
||||
- reproduce the current VM and public-network design first;
|
||||
- reach a zero-change plan before any apply;
|
||||
- protect the instance and boot volume from destruction;
|
||||
- treat migration to a private subnet as a separate reviewed change.
|
||||
- Region：`ap-osaka-1`，compartment 为 tenancy 根。
|
||||
- State：namespace `axckv9ylwqxr`，bucket `oci-k8s-free-tier-tfstate`，key `terraform.tfstate`。
|
||||
- 恢复源：2026-08-15 12:26:24 UTC 对象，25,261 字节，serial `249`，
|
||||
lineage `c945c6c4-ee01-d7b7-23f5-37207ea60609`，Terraform `1.15.8`。
|
||||
- 7 个受管资源保留原地址：`oci_core_instance.vm`、`oci_core_vcn.vcn`、
|
||||
`oci_core_subnet.public`、`oci_core_internet_gateway.igw`、`oci_core_route_table.public`、
|
||||
`oci_core_security_list.public`、`oci_limits_quota.free_tier_quota`。
|
||||
- 2 个数据源：`oci_core_images.ubuntu`、`oci_identity_availability_domains.ads`；保留 4 个原输出。
|
||||
- VM：`homelab-vm`，A1 Flex，2 OCPU / 12 GB RAM / 100 GB 启动盘，
|
||||
私网 `10.0.0.124`，恢复时公网 `129.225.138.179`。
|
||||
- VCN `10.0.0.0/16`，公共子网 `10.0.0.0/24`，默认路由经 Internet Gateway；
|
||||
入站保留 TCP 22、UDP 41641、ICMP type 3/code 4，出站全部允许。
|
||||
- 配额语句保留 A1 4 核 / 24 GB、10 个卷、200 GB 总存储限制；这些语句不是费用保证。
|
||||
- Bucket 自身不在 state 内，不由此根模块管理。
|
||||
|
||||
## 恢复设计
|
||||
|
||||
原变量、模块意图、provider 精确版本和生命周期规则无法从 state 完整恢复。
|
||||
本次选择并锁定 `oracle/oci 9.1.0`，提交 lockfile；这不是声称找回了原 provider 版本。
|
||||
资源间的 VCN、路由表、安全列表、子网和 DHCP 引用已重建。
|
||||
启动镜像固定为现有 image OCID，避免数据源选中更新镜像导致 VM 替换。
|
||||
新增 `prevent_destroy` 保护现有 VM；没有用 `ignore_changes` 掩盖配置差异。
|
||||
|
||||
Provider 使用本机 `~/.oci/config` 的 `DEFAULT` profile，可用变量覆盖 profile 和 region。
|
||||
metadata 经敏感变量传入，只保存在忽略的 `terraform.tfvars.json`，不进入版本库。
|
||||
State、plan、metadata 变量与 `.terraform/` 都不得提交；plan JSON 同样可能含敏感数据。
|
||||
保留原目录的恢复要求：保留 lineage/serial，先复现当前 VM 和公共网络设计，
|
||||
实际基础设施变更前达到严格零变更，并保护实例及启动盘；迁移私有子网须单独评审。
|
||||
已用既有 GPG 加密子密钥 `5A6A04D1B216C64E` 创建独立加密源备份
|
||||
`.recovery/source.tfstate.gpg`；本地原始副本的 lineage/serial 保持不变。
|
||||
|
||||
## 日常维护
|
||||
|
||||
旧 Terraform/CI 已由维护者确认停用，当前仓库已接管原 OCI Object Storage state。
|
||||
`versions.tf` 使用 OCI backend，直接连接原对象，未迁移本地恢复副本。
|
||||
认证沿用本机 OCI CLI 的 `DEFAULT` profile；不要在配置中写密钥。
|
||||
|
||||
```bash
|
||||
cd infrastructure/oci/terraform
|
||||
terraform init
|
||||
terraform validate
|
||||
terraform plan -input=false -out=change.tfplan
|
||||
# 核对计划后执行：
|
||||
terraform apply change.tfplan
|
||||
```
|
||||
|
||||
新 checkout 需从受限 state 副本提取 metadata 至被忽略的 `terraform.tfvars.json`。
|
||||
`prepare-local-state.py` 可执行这一步，同时保留 `.recovery/terraform.tfstate` 备份；
|
||||
当前 backend 使用远端对象，`.recovery/` 中的副本不再参与日常 plan/apply。
|
||||
下载前设置 `umask 077`，并使用 GPG 加密源备份；不要把本地副本上传覆盖远端。
|
||||
|
||||
## 恢复验证记录
|
||||
|
||||
Terraform 1.15.8、OCI provider 9.1.0 验证通过。
|
||||
恢复计划唯一更新是 VM metadata 的敏感标记，plan JSON 中 before/after 值相同。
|
||||
经授权 apply 后，本地完整刷新 plan 达到 `No changes`。
|
||||
旧 state 在 provider 刷新后补充 VM shape/VNIC、subnet IPv4 CIDR、route type 字段，
|
||||
这些读回差异没有产生基础设施修改计划。
|
||||
接管时重新连接原远端对象，因此新增实例计划也包含原 VM 的同一敏感标记归一化。
|
||||
|
||||
## AMD 实例
|
||||
|
||||
`oci_core_instance.amd` 配置为 `homelab-amd`，`VM.Standard.E2.1.Micro`，1 GB RAM，
|
||||
Ubuntu 24.04 x86_64，50 GB / 10 VPU 启动盘。复用现有公共子网和 SSH 公钥，
|
||||
没有复制 A1 实例的其他初始化内容，也不部署 Kubernetes。
|
||||
镜像固定为 `Canonical-Ubuntu-24.04-2026.08.25-0`，实例具有 `prevent_destroy` 保护。
|
||||
|
||||
创建前 API 确认大阪为 home region、机型计费类型为 `ALWAYS_FREE`，AMD 配额剩余 2 台。
|
||||
存储盘点只有 A1 的 100 GB 启动盘；已核对两个启动盘合计 150 GB，200 GB 免费额度内剩余 50 GB。
|
||||
免费额度跨启动盘和块存储共享；后续新增资源仍需重新核对实际占用。
|
||||
|
||||
实例已创建并确认 `RUNNING`，私网 `10.0.0.158`，公网 `129.225.176.134`。
|
||||
登录命令：`ssh [email protected]`（本次未验证 SSH 登录）。
|
||||
远端 state 已保存；创建后完整刷新 plan 为 `No changes`，退出码 0。

## DNS 登录入口
|
||||
|
||||
- ARM：`ssh [email protected]`
|
||||
- AMD：`ssh [email protected]`
|
||||
|
||||
公网 A 记录声明位于 `../dns/records.yml`，在 Cloudflare 上关闭代理，TTL 300 秒。
|
||||
当前通过 DNS API 管理，未加入 OCI Terraform state；公网 IP 变化时需同步记录。
|
||||
|
||||
## WireGuard/BGP 与 DN42
|
||||
|
||||
家中端点已从 laptop 迁移到 VyOS `192.168.10.2`，AMD 与 VyOS 同属 AS4242421811，
|
||||
通过独立 WireGuard 接口建立双栈 iBGP；laptop 保留原有 NEC BGP 和 OSPF，按路由经 VyOS 转发。
|
||||
Ansible 配置与运行方法见 [ansible/README.md](ansible/README.md)。
|
||||
|
||||
注册前缀 `172.21.111.160/27`、`fdd0:98df:15b0::/48` 已在内部路由中准备：
|
||||
VyOS `.161` / `::1`，AMD `.162` / `::2`，使用 loopback /32、/128。
|
||||
首个外部 DN42 peer 已接入 RoutedBits Osaka（AS4242420207），AMD 使用独立 `wg-dn42-1`
|
||||
和单 IPv6 MP-BGP 会话承载双栈；详见 [Ansible runbook](ansible/README.md)。
|
||||
外部明细留在 AMD，`172.20.0.0/14`、`fd00::/8` 汇总经 iBGP 下发 VyOS；IPv4 /14 再经 OSPF 下发 LAN。
|
||||
LAN 的 DN42 IPv6 /64 地址由 VyOS SLAAC 下发，fd00::/8 通过 RA RIO 分发，不通告 IPv6 默认路由。内部家中/OCI 业务路由不得向外部 DN42 邻居通告。
|
||||
|
||||
Terraform 管理 AMD NSG、VNIC 转发与 VCN 回程；Ansible 管理路由器/主机及 ARM 的 Tailscale
|
||||
回程例外。Docker 与 DN42 的 /14 地址重叠已迁出，见 [Docker runbook](../docker/README.md)。
|
||||
|
||||
VyOS 的 `wg42` 主 IPv4 已改为注册的 `172.21.111.161/32`，内部 BGP 改为
|
||||
单 link-local IPv6 会话承载双栈。三个 LAN 私网到 DN42 /14 由 VyOS 定向 masquerade，
|
||||
排除本 AS /27；OCI 业务保持原源地址。IPv6 不做 NAT，由 `ansible/dn42-ra.yml` 管理三个 LAN 的 SLAAC 与专用路由通告。

# VyOS ↔ OCI：WireGuard 与 DN42 内部 BGP
|
||||
|
||||
站点端已从 laptop 迁移到 VyOS `192.168.10.2`。VyOS 位于双层 NAT 后，主动连接
|
||||
`oci-amd.ddupan.top:51820`，keepalive 25 秒；LAN 访问 DN42 时在 VyOS 做定向 masquerade。
|
||||
主机配置由 Ansible 管理；OCI NSG、VNIC 转发和 VCN 回程路由由旁边的 Terraform 管理。
|
||||
|
||||
| 节点 | 接口 | 传输 IPv4 | 传输 IPv6 | ASN |
|
||||
|---|---|---|---|---|
|
||||
| VyOS | wg42 | 172.21.111.161/32 | fe80::1811:1/64（BGP） | 4242421811 |
|
||||
| AMD | wg-oci | 10.255.254.1/30（历史传输地址） | fe80::1811:2/64（BGP） | 4242421811 |
|
||||
|
||||
AMD 显式设置 `fe80::1811:2/64`；VyOS BGP 使用固定 `fe80::1811:1/64`，双方 AllowedIPs 包含
|
||||
`fe80::/64`。FRR 在 ULA 建邻时仍需接口具有 link-local 下一跳地址。
|
||||
|
||||
MTU 1380，Linux 使用 `Table = off`，WireGuard AllowedIPs 用于选 peer 与源地址校验，
|
||||
站点路由由 iBGP 安装。内外部均使用单条 IPv6 link-local 会话承载双 AFI，并启用 extended-nexthop。
|
||||
内部旧 IPv4/ULA BGP 邻居已退役；ULA 传输地址保留用于路由下一跳，不再用于建邻。
|
||||
VyOS 10.2.4 通过 `OCI-MP-IN` 的 `ipv6-next-hop prefer-global` 优先采用通告中的 ULA 下一跳，
|
||||
避免 link-local NHT 显示 overlay index unresolved、BGP 已建邻但路由未安装。
|
||||
|
||||
## 地址与通告边界
|
||||
|
||||
已注册 `172.21.111.160/27`、`fdd0:98df:15b0::/48`：
|
||||
|
||||
| 节点 | 路由器 IPv4 | 路由器 IPv6 |
|
||||
|---|---|---|
|
||||
| VyOS（IPv4 在 wg42，IPv6 在 lo） | 172.21.111.161/32 | fdd0:98df:15b0::1/128 |
|
||||
| AMD loopback | 172.21.111.162/32 | fdd0:98df:15b0::2/128 |
|
||||
|
||||
VyOS 为注册的 /27、/48 建立 distance 254 的 blackhole 聚合路由，保证精确前缀存在，
|
||||
避免未分配地址落入默认路由。已分配的本地地址及 AMD 的 /32、/128 优先于聚合。
|
||||
|
||||
内部通告严格过滤：
|
||||
|
||||
- VyOS → AMD：`192.168.10.0/24`、`10.60.0.0/24`、`10.61.0.0/24` 和注册 /27、/48。
|
||||
- AMD → VyOS：`10.0.0.0/24`、AMD 的注册 /32、/128，以及 DN42 汇总 `172.20.0.0/14`、`fd00::/8`。
|
||||
- VyOS 向 LAN OSPF 只重分发 OCI /24、DN42 /14 和注册 IPv4 /27，使用精确 route-map、E1 metric。
|
||||
既有直连 LAN/SDN 的 OSPF area 声明保持不变，不使用泛化的 redistribute connected。
|
||||
|
||||
**首个外部 peer 为 RoutedBits Osaka（AS4242420207），由 `dn42.yml` 单独管理。** 外部邻居使用独立的 import/export
|
||||
过滤，只对外通告注册 /27、/48；禁止把上述内部业务前缀的过滤器复用到外部邻居。
|
||||
入口使用 DN42 指南的保留地址、互联网络与前缀长度规则（IPv6 /44–/64），
|
||||
并优先拒收本 AS、LAN、OCI 前缀；尚未配置注册表 ROA 校验。外部明细留在 AMD，汇总通过 iBGP 下发 VyOS；IPv4 汇总再经 OSPF 下发 LAN。
|
||||
|
||||
每个外部 WireGuard peer 使用独立接口，BGP 可复用本机 loopback 地址。
|
||||
单接口多个 WireGuard peer 要求可明确区分的 AllowedIPs；多家 peer 都提供同一 DN42 路由范围时，
|
||||
使用独立接口让 BGP 决定出口，避免相同 AllowedIPs 抢占 peer。
|
||||
|
||||
## 执行
|
||||
|
||||
```bash
|
||||
cd infrastructure/oci/ansible
|
||||
export SSH_AUTH_SOCK="$(gpgconf --list-dirs agent-ssh-socket)"
|
||||
ansible-playbook site.yml --check --diff
|
||||
ansible-playbook site.yml
|
||||
ansible-playbook site.yml # 复跑应 changed=0
|
||||
```
|
||||
|
||||
`vyos.yml` 先在路由器本机生成密钥并保存，再交换公钥并增量应用 VyOS set 命令。
|
||||
VyOS native config 含私钥，因此相关模块使用 `no_log`，不把配置备份到 Git 或打印出来。
|
||||
AMD 私钥在 `/etc/wireguard/wg-oci.key`（0600），由本机 PostUp 加载，不返回控制机。
|
||||
首次 check mode 无法生成私钥，因此会跳过依赖不存在公钥的 Linux 配置渲染。
|
||||
|
||||
`retire-laptop.yml` 是迁移收尾：先检查 VyOS 邻居，再停止 laptop 的 wg-oci，
|
||||
删除试验邻居、三个新增 network 语句及专用防火墙链，保留 laptop 原 AS65001 ↔ NEC AS65000
|
||||
会话、原有 VPN 路由和 OSPF。旧私钥保留在 laptop 受限文件中，隧道和防火墙单元已禁用。
|
||||
|
||||
Linux 端 FRR 通过 `vtysh -f` 应用独立配置片段，另行 `write memory` 持久化；
|
||||
文件变更时重建受管邻居，未变更的重跑不重置会话。移除前缀时还须显式删除已退出管理的
|
||||
`network` 语句，不能只追加 set 命令，也不能清空整份 BGP 配置。
|
||||
|
||||
## OCI 回程与 Tailscale
|
||||
|
||||
VCN 虚拟路由器不参与主机间 iBGP；三个家中业务前缀的静态回程指向 AMD Private IP OCID。
|
||||
首次启用时必须先将 VNIC `skip_source_dest_check` 设为 true，OCI 才接受该私有 IP 为路由目标。
|
||||
当前 Terraform 的 route table → subnet → instance 依赖使首次引导需要先设置该标志。
|
||||
重建 AMD 后须重新查询并更新 `amd_router_private_ip_ocid`。
|
||||
|
||||
ARM 接受 Tailscale 家中子网路由，table 52 原本抢走回程。
|
||||
Ansible 在 ARM 设置 priority 5101–5103、仅匹配这三个目的前缀的 `lookup main` 规则，
|
||||
让这些流量使用 OCI 网关→AMD；其他 Tailscale 地址保持原路径。
|
||||
AMD 的 Zebra route-map 仅为本机发起的 BGP 业务流量选择 `10.0.0.158` 源地址，不改写转发源地址。
|
||||
|
||||
## Docker 地址冲突
|
||||
|
||||
DN42 使用 `172.20.0.0/14`。原 laptop Docker 的四个 /16 已清除，默认池改为 `172.28.0.0/16`，
|
||||
详见 [Docker runbook](../../docker/README.md)。最长前缀匹配决定路由，但不能解决两套网络实际
|
||||
地址重叠；不能只检查本 AS 注册的 /27 而忽略其他 DN42 注册前缀。
|
||||
|
||||
## 验证与停用
|
||||
|
||||
```bash
|
||||
# VyOS operational mode
|
||||
show interfaces wireguard wg42 summary
|
||||
show bgp summary
|
||||
show ip route 172.21.111.162/32
|
||||
show ipv6 route fdd0:98df:15b0::2/128
|
||||
# AMD
|
||||
sudo wg show wg-oci latest-handshakes
|
||||
sudo vtysh -c 'show bgp summary'
|
||||
ping 192.168.10.4
|
||||
ping -I 172.21.111.162 172.21.111.161
|
||||
ping -6 -I fdd0:98df:15b0::2 fdd0:98df:15b0::1
|
||||
```
|
||||
|
||||
业务网段测试应使用业务源地址；DN42 loopback 测试使用注册地址。
|
||||
LAN 已通过 `dn42-ra.yml` 部署 DN42 SLAAC 与专用 RIO，不发布 IPv6 默认路由；OCI VCN 保持原配置。
|
||||
停用或回滚须同时处理 BGP、WireGuard、OSPF 重分发、VCN 回程和 ARM 例外规则，
|
||||
不能仅停止隧道后留下静态回程指向不可达节点。
|
||||
|
||||

## 迁移验收
|
||||
|
||||
2026-09-14：
|
||||
|
||||
- VyOS IPv4 iBGP 收到 OCI /24、AMD /32，通告三个家中前缀与注册 /27；IPv6 会话双方各收到一条前缀。
|
||||
- 两端 DN42 loopback IPv4、IPv6 互通；IPv6 本次采样约 3.1 ms。
|
||||
- laptop 的 `10.0.0.0/24` 与 `172.21.111.160/27` 经 OSPF 指向 `192.168.10.2`，不再使用旧隧道。
|
||||
- PVE1 可访问 ARM 私网和 AMD 的 DN42 IPv4；AMD 可访问 PVE1、`10.60.0.1`、`10.61.0.1`。
|
||||
- laptop 旧 WireGuard 和专用防火墙 service 已停止/禁用，原 NEC BGP 会话保留。
|
||||
|
||||
LAN 网关可能返回 ICMP Redirect，提示客户端将 VyOS 作为同网段下一跳；这是既有 LAN
|
||||
拓扑的正常结果，没有为此修改客户端或网关的 redirect 策略。
|
||||
|
||||
## AMD 外部 DN42 首个接口
|
||||
|
||||
2026-09-15 已通过 `ansible-playbook dn42.yml` 准备独立监听：
|
||||
|
||||
- 接口：`wg-dn42-1`，UDP endpoint：`oci-amd.ddupan.top:51821`（`129.225.176.134:51821`）。
|
||||
- 公钥：`YQ/X3QmNocnr0u4aUm5qhcV328StSNtg+ULd9AKCdhQ=`。
|
||||
- 私钥仅保存在 AMD `/etc/wireguard/wg-dn42-1.key`，由 root 受限目录保护，不返回控制机。
|
||||
- `wg-quick@wg-dn42-1` 开机启动；主机入站规则随接口启停，OCI NSG 规则由 Terraform 管理。
|
||||
- Link-local：`fe80::1811:2/64`，本机作用域为 `%wg-dn42-1`。首个 peer 使用单条 IPv6 BGP 会话承载双栈（MP-BGP + RFC 8950 extended next hop）。
|
||||
- 对端：AS4242420207，`router.osa1.routedbits.com:51811`，link-local `fe80::207`。
|
||||
- 对端公钥：`96PwUEGi/ijdmKO+IjuZ+J6DeykuTRukZD5atajfeH4=`。
|
||||
- WireGuard 使用 `Table = off`；AllowedIPs 为 `fe80::/64, 172.20.0.0/14, 10.0.0.0/8, 172.31.0.0/16, fd00::/8`，keepalive 25 秒。
|
||||
- 双 AFI 共用 IPv6 TCP 会话并启用 extended-nexthop；每 AFI maximum-prefix 10000，出口只允许注册 /27 和 /48。
|
||||
- 本机发起 DN42 流量使用注册地址作为 preferred source，不做 NAT。
|
||||
- Ubuntu 自带 FRR 8.4.4 不满足 [DN42 FRR 指南](https://dn42.dev/howto/frr) 的 link-local 版本要求。
|
||||
`tasks/frr-dn42.yml` 使用官方 frr-10.7 软件源，固定 10.7.1；升级前配置仅在 AMD `/var/backups/frr-before-dn42` 备份。
|
||||
|
||||
原 `wg-oci:51820` 继续承载与 VyOS 的内部互联。
|
||||
|
||||
2026-09-15 接入验收：WireGuard 握手与 `fe80::207%wg-dn42-1` 连通；FRR 10.7.1
|
||||
会话 Established，双方已协商 IPv4/IPv6 AFI 与 extended nexthop。采样接收 IPv4 1174、IPv6 1273 条，
|
||||
对外仅通告 `172.21.111.160/27`、`fdd0:98df:15b0::/48`。AMD 无需显式指定源地址，
|
||||
即可访问对端 `172.20.19.78`、`fdb1:e72a:343d::f`，各 3/3 回复，约 1 ms；
|
||||
IPv4 内核路由下一跳为 `via inet6 fe80::207 dev wg-dn42-1`。内部 VyOS 双栈 BGP 会话已恢复。
|
||||
|
||||
## 向 LAN 分发 DN42 汇总
|
||||
|
||||
`site.yml` 在 AMD 生成 `172.20.0.0/14`、`fd00::/8` 的 BGP aggregate，并通过内部精确
|
||||
prefix-list 通告 VyOS。不使用全局 `summary-only`，避免抑制对外通告的注册 /27、/48；
|
||||
对外出口过滤仍只允许这两个注册前缀。AMD 保留外部明细与汇总丢弃路径，无匹配明细的流量
|
||||
在 AMD 丢弃。汇总只要仍有覆盖的 BGP 明细（包括本 AS 注册前缀）就可能存在，不能作为外部
|
||||
peer 在线状态指示。自己的 /27、/48 更具体，继续指向本地站点。
|
||||
|
||||
VyOS 将 IPv4 /14 通过既有 OSPF E1 分发到 LAN；IPv6 /8 通过 RA 的 RIO 分发至接受该选项的客户端。
|
||||
LAN 的 DN42 IPv6 地址通过 SLAAC 自动分配。
|
||||
当前 LAN IPv4 客户端访问 DN42 /14 由 VyOS 定向 masquerade 到 `172.21.111.161`；
|
||||
IPv6 使用 SLAAC 分配的注册地址直接路由。
|
||||
AMD 只放行注册前缀在内部 `wg-oci` 与外部 `wg-dn42-1` 之间转发。
|
||||
|
||||
2026-09-15 汇总验收：VyOS 双栈 BGP 分别收到 /14、/8，下一跳为 AMD；
|
||||
laptop 的 `172.20.0.0/14` 为 OSPF 路由，经 `192.168.10.2 dev br0`。
|
||||
使用 VyOS 注册的 /32、/128 作为源，经 AMD 访问 RoutedBits 的双栈地址各 3/3 回复，
|
||||
约 4–5 ms。`site.yml` 执行成功，ARM 无变更；LAN 地址配置保持原状。
|
||||
|
||||
## DN42 DNS 转发
|
||||
|
||||
`ansible-playbook dn42.yml dn42-dns.yml` 管理入口路由和 VyOS DNS。LAN 的 Blocky
|
||||
(`192.168.10.127`) 将 `.dn42`、172.20–23 的 IPv4 反向区和 `d.f.ip6.arpa`
|
||||
转给 VyOS `192.168.10.2:53`。VyOS 仅接受三个内部 LAN 网段，使用注册地址
|
||||
`172.21.111.161` / `fdd0:98df:15b0::1` 发起递归转发，不做 NAT。
|
||||
|
||||
| 上游 | IPv4 | IPv6 |
|
||||
|---|---|---|
|
||||
| a0.recursive-servers.dn42 | 172.20.0.53 | fd42:d42:d42:54::1 |
|
||||
| a3.recursive-servers.dn42 | 172.23.0.53 | fd42:d42:d42:53::1 |
|
||||
|
||||
两个上游的双栈地址均配置，递归请求设置 RD；转发域配置 NTA，避免使用公网根信任链
|
||||
验证 DN42 私有命名空间。本地转发器不声明已完成 DN42 DNSSEC 信任锚验证。
|
||||
IPv4 anycast /32 需要允许四个 `172.2x.0.0/24` 中的 /28–/32，不能只保留 /14 的 /21–/29。
|
||||
新增互联网络明细仅由 AMD 接收；LAN 汇总仍是既定 /14、通过 RIO 通告的 IPv6 /8。
|
||||
NEC 备用 DNS 与 k3s CoreDNS 本次未修改。
|
||||
|
||||
DNS 验收（2026-09-15）：从 VyOS 用注册地址直查 a0/a3 的四个双栈地址均获得回复。
|
||||
LAN 查询 Blocky 可得到 a0 的 A、a3 的 AAAA；AD 与公网域名正常，Blocky healthy。
|
||||
VyOS DNS playbook 复跑 changed=0；AMD 已应用完整入口规则。
|
||||
|
||||
## VyOS LAN 到 DN42 masquerade
|
||||
|
||||
规则 18100 排除本 AS `172.21.111.160/27`；18110、18120、18130 分别匹配三个 LAN
|
||||
源网段，目的仅 `172.20.0.0/14` 且出口 `wg42`，translation 为 `masquerade`。
|
||||
为使 masquerade 选中注册地址，`172.21.111.161/32` 从 lo 移到 wg42，并移除
|
||||
`10.255.254.2/30`；不能在 wg42 仍以传输私网地址为主 IPv4 时直接启用 masquerade。
|
||||
现有 OCI 业务互联继续保留原源地址，DNS 转发使用的 `172.21.111.161` 保持可用。
|
||||
AMD 仍仅允许 DN42 注册源前缀进入外部隧道，不在 AMD 做第二次 NAT。
|
||||
|
||||
2026-09-15 masquerade 验收：laptop `192.168.10.127` 到 RoutedBits `172.20.19.78`
|
||||
3/3 回复约 4.7 ms，VyOS NAT 表显示转换为 `172.21.111.161`；到 ARM `10.0.0.124`
|
||||
3/3 回复约 4.2 ms，NAT 表确认保留 `192.168.10.127`。
|
||||
内部 link-local 单会话双 AFI 已建立；外部 peer 保持独立接口和精确出口。
|
||||
|
||||
## LAN DN42 IPv6 RA（不发布默认路由）
|
||||
|
||||
执行 `ansible-playbook dn42-ra.yml`，为三个 LAN 启用 SLAAC：
|
||||
|
||||
| LAN | VyOS 接口 | 前缀 | 路由器地址 |
|
||||
|---|---|---|---|
|
||||
| 192.168.10.0/24 | eth0 | fdd0:98df:15b0:10::/64 | fdd0:98df:15b0:10::1 |
|
||||
| 10.60.0.0/24 | eth1 | fdd0:98df:15b0:60::/64 | fdd0:98df:15b0:60::1 |
|
||||
| 10.61.0.0/24 | eth2 | fdd0:98df:15b0:61::/64 | fdd0:98df:15b0:61::1 |
|
||||
|
||||
Router Lifetime 为 **0**，不发布 `::/0`；PIO 开启 on-link 与 autonomous 标志，
|
||||
preferred lifetime 14400 秒、valid lifetime 86400 秒。RIO 只包含 `fd00::/8`，
|
||||
有效期 180 秒；RA 周期 10–30 秒。不发布 RDNSS、DNSSL、DHCPv6 标志或链路 MTU，
|
||||
保留客户端现有 DNS 和公网出口。IPv6 经 VyOS→AMD→DN42 直接路由，不做 NAT66。
|
||||
现有 /48 对外通告及内部回程已覆盖这三个 /64，无须泄漏每个 LAN 的明细到外部。
|
||||
|
||||
客户端须支持并接受 RIO。当前 laptop 的 br0 `accept_ra=0`、`forwarding=1`，
|
||||
不会自动配置；本次保留其网络设置。Linux 路由主机如需接受 RA，需要在自身网络管理
|
||||
配置中显式启用，并允许至少 /8 的 RIO（`accept_ra_rt_info_max_plen`）。
|
||||
关闭 RA 时注意 PIO 的有效期；不要只删路由器接口地址而留下仍有效的客户端地址。
|
||||
|
||||
2026-09-15 RA 抓包验收：主 LAN 收到不带标签的 `:10::/64`；VLAN 100/110
|
||||
分别携带 `:60::/64`、`:61::/64`。三者 Router Lifetime 均为 0，PIO 为 onlink/auto，
|
||||
RIO 为 fd00::/8、180 秒，没有 DNS 或默认路由通告。`dn42-ra.yml` 复跑 changed=0。
|
||||
同一 LAN 上的临时 Linux 测试客户端自动获得地址与 RIO，无 IPv6 默认路由；测试后自动删除。
