一、项目背景
比赛模拟了某大型公司企业网通过广域网连接数据中心的场景。
考虑到网络冗余和流量负载均衡的需求,企业网部署MSTP、防火墙双机热备用于承载web业务和Internet访问业务。同时,为了满足员工的无线办公需求,工程师需要部署WLAN设备于企业网内,用于访问Internet。
在使用丰富的网络资源建设企业网络和数据中心网络的时代大背景下,工程师们证面临严峻的安全问题,NGFW可以部署于企业网络和数据中心网络出口有利于降低安全风险,以帮助实现安全且高效的网络管理。
该企业的私有云部署在总部数据中心机房,企业的各类业务系统都部署在其私有云上,其中企业的OA系统所在的web服务器部署在总部的数据中心,企业各分支需要通过MPLS VPN访问远端数据中心的Web-Server,并且出于安全因素,Web-Server的私网地址不通告到广域网,而是通过一个外部公网地址100.1.1.1提供访问,Web-Client到Web-Server的流量需要在防火墙FW3上做目的地址转换,转换成Web-Server私有地址实现访问。
为实现数据中心租户位于不用子网的业务虚拟机互通,这里业务虚拟机为VM1和VM2,需要在数据中心部署GRE隧道,以打通VM1和VM2的三层通道。
广域网为企业的内网和远端总部数据中心提供链接,提供在广域网上部署MPLS VPN实现企业的互联网专线功能,以确保在广域网上的业务隔离的效果。

任务6:公网静态路由配置(路由可参考图2-2、图2-3及描述)
- 为了实现将去往Internet的流量和去往数据中心Web-server的流量引流到广域网上,需要在FW1和FW2上配置静态路由实现。PE1的主接口用于接收Internet流量,PE1的子接口用于接收Web-Server流量。在PE1上配置两台指向WLAN客户端的回程静态路由,回程路由需要指向FW1和FW2实现负载分担,用于引导Internet回程流量。
- 因需要发布global地址段到VPN,所以需要在防火墙FW3上配置到Web-Server global地址100.1.1.1的静态黑洞路由,用于引导Web-Server的VPN流量。
- 在FW3上配置一条缺省路由,引导Web-Server从数据中心到企业内网的回程流量。

任务7:公网动态路由配置
- 在PE1、P、PE2组成的广域网里部署ISIS路由协议,进程ID为1,ISIS域配置为Level-2层,区域ID号为01,systemid值自行规划。要求PE1的Loopback0和GE0/0/2,P路由器Loopback0、GE0/0/1和GE0/0/2,PE2的Loopback0和GE0/0/1使能ISIS协议。
- 为了提高网络安全性,需要配置对LSP、CSNP、PSNP报文MD5认证功能,认证密码为ICTEXAM。
- DC数据中心部署OSPF,DC内所有路由器均部署在ospf area 0骨干区域,要求FW3的GE1/0/1,DC-GW的loopback0、GE0/0/1、GE0/0/2和GE0/0/3,Leaf1的Loopback0、GE0/0/2和GE0/0/3,Leaf2的loopback0和GE0/0/3所在的地址段发布到OSPF区域。
- FW3往OSPF路由域发布缺省路由引导Web-Server服务器到企业内网的回程流量。要求当FW3与PE2的链路中断后,FW3可以同步停止发布缺省路由,避免产生无效流量。
- PE1的loopback0和P路由器的loopback0配置为IBGP邻居,PE2的loopback0和P路由器的loopback0配置为IBGP邻居,P路由器配置IBGP邻居组,添加PE1和PE2为邻居组成员,P路由器配置为反射器RR,PE1和PE2是P路由器的客户端。PE2的GE0/0/3和Internet路由器的GE0/0/3配置为EBGP邻居。把Internet路由器上的loopback0地址提供EBGP通告给对端路由器PE2,引导流量上行。(路由可参考图2-2及描述)

任务8:MPLS VPN(路由可参考图2-3及描述)
- PE1的loopback0和P路由器的Loopback0配置为MP-IBGP邻居,PE2的loopback0和P路由器的loopback0配置MP-IBGP邻居,P路由器配置为VPN反射器vRR,PE1和PE2是P路由器的客户端。为了能将路由顺利传递,需要在P路由器上配置undo policy vpn-target。
- PE1、P、PE2使能MPLS和MPLS LDP,并将各自的loopback0接口地址配置为MPLS LSR ID。PE1的GE0/0/2,P路由器的GE0/0/1和GE0/0/2,PE2的FE0/0/1均使能MPLS和MPLS LDP。
- PE1和PE2配置VPN实例,命名为ToDC,RD值为100:1,Export RT和Import RT均为200:1。把PE1的GE0/0/3.1接口绑定到PE1的VPN实例ToDC,PE2的GE0/0/2绑定到PE2的VPN实例ToDC。
- 在PE1的VPN实例ToDC内配置静态路由,目的网段为Web-Client地址段192.168.0.0/16,吓一跳指向FW1和FW2的GE1/0/3.1,以实现Web-Server回程流量的负载分担。将配置的两条等价静态路由引入到VPN实例ToDC中,让MP-IBGP通告给PE2,引导Web-Server的回程流量。
- PE2的VPN实例ToDC上的接口GE0/0/2与FW3的GE1/0/2配置为EBGP邻居,通过EBGP邻居交换Web-Server业务路由。
