CCNP认证概述

CCNP认证(思科认证网络专业人员)表示通过认证的人员具有丰富的网络知识。获得CCNP认证的专业人员可以为具有100到500多个节点的大型企业网络安装、配置和运行LAN、WAN和拔号访问业务。他们可以使用的协议包括，但不限于IP, IGRP, IPX, Async Routing, AppleTalk, Extended Access Lists Route, IP RIP, Redistribution, RIP, Route Summarization,OSPF, VLSM, BGP, Serial, Frame Relay,ISDN, ISL, X.25, DDR,PSTN, PPP, VLAN, Ethernet, Access Lists, 802.10, FDDI, Transparent 和Translational Bridging.

考取CCNP认证的前提是必须首先通过CCNA认证。CCNP考试从1998年设立以来经过多次更改，目前考取最新CCNP有两种途径：一是801+811+821+831，另外一种是891+821+831。
