静态路由选择解释
给定一张 IPv4/IPv6 路由表和目的地址，逐条说明最长前缀、metric、同级候选及拒绝动作，保留完整报告与原件。
请从原始路由文本手工整理单一静态表。工具解释声明的排名；缓存、重定向和现网策略需结合真实系统检查。

开始之前
给定一张 IPv4/IPv6 路由表和目的地址，逐条说明最长前缀、metric、同级候选及拒绝动作，保留完整报告与原件。
如何使用
- 选择粘贴或文件模式。
- 输入声明路由与本次目的地址。
- 逐地址核对匹配理由和全部同级候选。
- 下载原件、完整 JSON 与 CSV，结合实际系统配置排查。
支持范围与限制
明确选择粘贴或单个 UTF-8 JSON 文件；只处理当前模式，原始输入最多 1 MiB。拒绝 BOM、损坏 UTF-8、重复键和有损数值。
1–4096 条路由、1–256 个目的地址，路由与目的地址的乘积最多 16384。id 和 interface 为 1–128 个 UTF-16 单元；metric 为 0–4294967295 整数，hopLimit 为 0–255 整数。
支持 unicast、blackhole、unreachable、prohibit。unicast 可声明同地址族 nextHop；CIDR 主机位会规范化并标记。IPv4 映射 IPv6 保持 IPv6 地址族。
只按最长前缀、再按最小 metric 筛选。保留全部同级候选；顺序和 hopLimit 不打破平局，混合动作平局明确标记。
完整 JSON、CSV、原件与复制文本合计最多 16 MiB；CSV 对公式前缀加单引号，JSON 与原件保持原值。超限整份拒绝。
此声明表不包含实际系统策略、缓存、重定向、接口状态或包级 ECMP；不能据此证明某个真实数据包的路径或修复系统问题。
原始 ip-route 文本需手工整理成声明的 JSON 字段。工具只读单一静态表，不能修复现网路由、缓存、重定向或策略。
只处理当前活动的粘贴或文件来源。活动文件名允许512 UTF-8字节、MIME标签128字节；原始输入保持逐字节完整，并提供来源SHA256。
10秒整体绝对期限从元数据检查和原生文件读取前开始，覆盖Worker加载到发布结果。取消、超时或换源会清空全部旧产物；完整来源保留，可再次运行。
完整JSON报告、公式安全CSV、原始输入和复制文本合计16 MiB。生成大字符串前先预留输出字节；typed报告和表格JSON另有16 MiB工作量上限，不发布部分输出。

出现问题时
保留声明原件，按错误修正地址、字段或数值范围；超预算时拆分目的地址。取消或失败不交付部分报告，可保留同一输入重试。
常见问题
hopLimit 会改变候选排序吗？
不会。它只被保留，不作为本模型的路由排名条件。
两个候选完全同级时会选第一条吗？
不会。结果保留全部同级候选和动作歧义；包级选择需要实际系统的额外信息。
