HCIP中期实验

Code-42023-11-26 8:42

需求

1、该拓扑为公司网络，其中包括公司总部、公司分部以及公司骨干网，不包含运营商公网部分。

2、设备名称均使用拓扑上名称改名，并且区分大小写。

3、整张拓扑均使用私网地址进行配置。

4、整张网络中，运行OSPF协议或者BGP协议的设备，其Router-id值为设备名数字号，例如R1的Router-id为1.1.1.1、

5、OSPF路由宣告部分选择接口宣告方式，例如192.168.100.1 0.0.0.0；BGP仅宣告用户网段。

6、IBGP部分使用环回建立邻居，EBGP部分使用直连链路建立邻居，所有运行BGP的设备都需要建立邻居。

7、R1、R2、R5、R6、R7、R8、R9、R10需要配置环回接口，环回接口IP为设备名数字号，掩码为32，例如R2的环回接口为2.2.2.2/32

8、所有PC的IP地址均手工配置。

公司分部：

1、PC5和PC6属于不同VLAN

2、SW4是一个二层交换机

3、SW3是一个三层交换机

4、R9是分部出口路由器

5、分部使用OSPF进程200达到分部网络全网可达

6、公司分部出口设备运行BGP协议连接骨干网络，AS号为100

7、因AS-PATH属性原因，总部与分部路由会学习不到，使用命令如（peer 10.10.10.10 allow-as-loop，仅在总部与分部设备上配置即可），将允许AS号重复。

公司总部：

1、交换机为二层交换机

2、PC1和PC2属于一个网段，PC3和PC4是一个网段

3、R3和R4分别是下方PC的网关路由器

4、为保障公司总部到骨干网络的连通性，公司总部使用双路由器双出口的方式接入骨干网

5、为保障公司总部网络内部具备负载，R1、R2、R3、R4设备均作为设备冗余，并使用全连接的方式进行路由选路

6、总部内网使用OSPF进程100达到全网可达，OSPF需要宣告环回。

7、公司总部双出口设备运行BGP协议连接骨干网络，AS号为100

8、因为R1和R2重发布时会出现次优路径，需要修改BGP路由优先级，使用命令（preference 140 255 255，仅在总部设备上配置即可），配置位置在iPv4-family unicast中。

公司骨干网：

1、为保障公司网络连通性，骨干网络考虑设备冗余操作，连接总部使用双路由器，骨干网络部分路由器之间使用双联路方式

2、骨干网设备运行OSPF协议达到骨干网全网可达，进程号为10。

3、骨干网设备运行BGP协议，AS号为200。使用全连接方式建邻。

优化：

1、为达到分流互备效果，公司总部业务部访问分部流量走R1，R2做备份；公司总部工程部访问分部流量走R2，R1做备份，并要求来回路径一致。

2、公司总部双出口流量均流向R5，R6做备份。来回路径一致。

3、OSPF重发布时，更改类型为Type-1

4、所有策略名称为policy-1

5、更改开销时，全部更改为10
