Exam : H3C H3CTE
Title : H3C Certified Troubleshooting Expert
一、实验题

1.
要求
1 、总部运行ospf，总部和两个分部之间运行BGP，RT1和RT2运行IBGP使用loopback端口为接口地址。由于分部的的网络比较简单要求分部的路由发布到BGP中。
2、分部B到总部通过ipsec+tunnel的模式。IPsec 采用野蛮模式，只对业务流进行加密。
3、总部的ospf和BGP互相发布后会形成路由环路，RT1 和RT2通过 BGP协议
4、总部和分部A，正常情况下业务通过FR链路到分部A，OA流通过PPP线路到分部A
5、当FR链路不能用的时，业务流通过ppp链路到分部A，此时业务流和OA流都在 PPP链路。要在RT2和RT4上做QOS保证业务流1M 的带宽。通过CBQ,对进来的业务打dscp afc4的标记，在以太网进口上对业务流打标记，在出口上进行带宽保证
6、要求两个分部之间进行隔离，通过AS-path-acl进行网络隔离
7、分部A 通过vrrp实现，当fr链路断掉时候业务流，自动切换到ppp的链路上。总部通过bgp动态路由实现路由切换
8、通过 local-preference和MED两个参数实现业务流走FR，OA 流走PPP
9、RT2和RT4之间的ppp链路采用chap认证
10、总部和分部的bgp要求验证
11、为了保证总部路由不产生环路，要求在RT1＆RT2上通过BGP的preference
进行调整。
答案：
RT1: 1、RT1 与RT3 通过专线连接，两端设备均为DTE，无法建立连接，将RT1 设置为DCE 设备，在接口3/0 配置fr interface-type dce 。
2、RT1 加密访问控制列表3001 定义数据流量不准确，本段业务网段地址为160.0.0.0/24，分部B 业务网段为160.2.0.0/24，。具体参数如下：acl number 3001 rule 0 permit ip source 160.0.0.0 0.0.255.255 destination 160.2.0.0 0.0.255.255
　　rule 1 deny ip
3、RT1 IKE 采用野蛮方式，数据需要进行双向访问，RT1 没有配置远端接入地址，须配置RT5 的接入端地址作为局段地址
4、RT1 IKE 采用野蛮方式，使用网关名字进行协商，RT1 没有配置本段的网关名字，需要配置。
ike local-name rt
5、RT1 没有在接口上应用安全策略组，在GRE 通道应用安全策略。interface Tunnel0 ipsec policy rt5
6、RT1 OSPF 进程1 中，区域0 宣告的网段，子网掩码配置不正确，导致无法建立正确的邻居关系。调整10.0.0.0 子网掩码为0.0.255.255
7、RT1 与RT2 之间使用LOOOPBACK 地址接口来建立IBGP 关系，使用LOOPBACK 地址作为接口地址以后存在1.1.1.1 与2.2.2.2 网络层上不通的问题，无法正常的建立邻居关系，可以通过OSPF 将LOOOPBACK 地址宣告出去，保证连通性。RT1： Ospf 1 Area 0 Network 1.1.1.1 0.0.0.0 RT2： Ospf 1 Area 0 Network 2.2.2.2 0.0.0.0
8、RT1 路由器没有配置EBGP 的认证，不能保证连接的安全性，需在TCP 连接时配置MD5 认证，修改如下：
Bgp 65000
peer 10.1.13.2 password simple h3c
peer 10.2.15.2 password simple h3c
路由器RT2 、RT3 、RT4 、RT5 需要做同样的验证配置。
9、策略路由配置错误，R1、R2 的业务网段本地优先级与开销相同，R2OA 网段没有进行流量匹配，不符合业务流通过FR 传输，OA 通过ppp 链路进行传输的要求。修改后策略如下：R1：
route-policy YEWU permit node 10
if-match acl 2001
apply local-preference 200
apply cost 50
route-policy YEWU permit node 20
if-match acl 2002
apply local-preference 100
apply cost 200
R2：
route-policy YEWU-OA permit node 10
if-match acl 2001
apply local-preference 100
apply cost 100
route-policy YEWU-OA permit node 20
if-match acl 2002
apply local-preference 200
apply cost 100
10、RT1 、RT2 的路径访问控制列表配置不正确，无法实现分部只有总部进行通信的要求，而且路径访问控制列表在BGP 协议中中没有应用。配置如下：
RT1： ip as-path-acl 1 permit ^$
bgp 65000
peer as65002 as-path-acl 1 export
RT2：
ip as-path-acl 1 permit ^$
bgp 65000
peer as65001 as-path-acl 1 export
11、RT5IKE 需要采用野蛮方式，使用网关名字进行协商，需要配置本端的网关名字。
12、RT5 加密访问控制列表定义数据流量不准确，而且与RT1 不是互为镜像关系，
acl number 3001 rule 0 permit ip source 160.2.0.0 0.0.255.255 destination 160.0.0.0 0.0.255.255 rule 1 deny ip
13、RT5 没有在接口上应用安全策略组，在GRE 通道应用安全策略。interface Tunnel0 ipsec policy rt1
14、RT2 与RT4 进行PPP 连接，配置本地用户名，服务类型为ppp，命令为local-user h3c service-type ppp RT3 上的错误：
1、配置e0/0.11 上的vrrp 优先级为120，vrrp vrid 11 priority 120
Switch2 错误： 1、创建vlan 11 、12
2、将trunk 口改为permit vlan all
