网站导航栏制作,镇江市建设审图网站,做网站用啥语言,建立网站需要分几部进行前期综合实验 一、实验拓扑二、实验要求三、实验思路四、实验步骤1、配置接口IP地址2、交换机配置划分vlan10以及vlan203、总部分部#xff0c;骨干网配置OSPF分部总部骨干网 4、配置BGP建立邻居关系总部骨干网分部 5、发布用户网段6、将下一跳改为本地7、允许AS重复8、重发布… 前期综合实验 一、实验拓扑二、实验要求三、实验思路四、实验步骤1、配置接口IP地址2、交换机配置划分vlan10以及vlan203、总部分部骨干网配置OSPF分部总部骨干网 4、配置BGP建立邻居关系总部骨干网分部 5、发布用户网段6、将下一跳改为本地7、允许AS重复8、重发布9、修改BGP优先级10、优化1修改cost值2修改MED值3修改为type1 一、实验拓扑 二、实验要求
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 0.0.0.0BGP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 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链路路方式 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R1R2做备份公司总部工程部访问分部流量走R2R1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R5R6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
三、实验思路 四、实验步骤
1、配置接口IP地址
