About the 路由与交换助理 certification
路由与交换助理认证验证你能够设计、配置、加固和排障构成每个企业骨干网络的交换与路由网络。你将从第二层展开推理:VLAN 与 802.1Q 干道、生成树协议族(STP/RSTP)、EtherChannel 链路聚合、MAC 地址表、端口安全,以及使用交换虚拟接口实现的 Inter-VLAN 路由。 上升至第三层,考试涵盖路由表与最长前缀匹配转发、静态路由与动态路由、管理距离与度量值,以及内部网关协议——RIP、OSPF(区域、LSA、DR/BDR 选举)和 EIGRP 概念——以及 BGP 基础。你将手工完成 VLSM 与子网划分,设计路由汇总,编写并排序 ACL,配置 NAT/PAT,以及操作 DHCP、DNS 和首跳冗余协议(HSRP/VRRP)。考纲还包括 IPv6 路由基础、QoS 入门,以及按 OSI 层定位故障的结构化排障方法论。 本认证厂商中立:相关概念与 CLI/配置模式可在 Cisco、Juniper、Arista 及开放平台间自由迁移。考生应已持有网络基础认证,或具备 OSI 模型、IP 寻址和基础设备配置的同等实操经验。
What you will learn
The official 路由与交换助理 study course covers:
- Switching, VLANs & Trunking — How switches forward frames, how VLANs segment a LAN, how 802.1Q trunks carry many VLANs, and how to route between them.
- Spanning Tree & Link Aggregation — Preventing Layer 2 loops with STP/RSTP, electing the root, protecting the edge, and bundling links with EtherChannel.
- IP Routing Fundamentals — The routing table, longest-prefix match, static vs dynamic routing, administrative distance and metrics.
- IGPs and BGP — RIP, OSPF (areas, LSAs, DR/BDR), EIGRP concepts, and the basics of BGP between autonomous systems.
- Subnetting, VLSM & Summarization — IPv4 subnetting by hand, VLSM for efficient design, route summarization, and IPv6 addressing basics.
- Services, Security & Troubleshooting — ACLs, NAT/PAT, DHCP and DNS operations, FHRP (HSRP/VRRP), QoS basics and a structured troubleshooting method.
