存根区域
类型 5 LSA 不会泛洪至存根区域。ABR 将默认路由通告到它所连接的存根区域。存根区域路由器使用默认路由到达外部目标。
1. 启用 OSPF 路由并进入 ROUTER-OSPF 模式，从 1 到 65535。
router ospf instance number
2. 在 ROUTER-OSPF 模式下将区域配置为存根区域。
area area-id stub [no-summary]
• area-id— 将 OSPF 区域 ID 输入为 A.B.C.D 格式或数字（从 1 到 65535）的 IP 地址。
• no-summary —（可选）输入以防止 ABR 将摘要 LSA 发送至存根区域。
