华为eNSP搭建的综合实验
综合实验
拓扑如图：
实验需求：
1.网络地址规划为200.102.Y.0，x为学号编号，所有路由器均创建环回接口
2.R1-R2-R3使用MGRE网络 OK
3.R5-R6点对点链路，使用chap双向认证
4.按图配置动态路由协议
5.area 2中不得出现5类LSA
6.R7-R8之间EBGP邻居关系，R8-R9-10之间建立全互联的IBGP邻居关系，R10-R11之间建立EBGP邻居关系
7.R11另外创建3个环回接口192.168.1.0 192.168.2.0 192.168.3.0 网段
8.网络优化，全网可达
实验配置：
1、 合理规划IP地址，所有路由器创建环回接口
2、 R1-R2-R3使用MGRE网络
这里使用200.102.1.1、200.102.2.1、200.102.3.2作为接口地址，使用10.1.1.1、10.1.1.2、10.1.1.3，作为隧道地址，进行hub-spoke的MGRE配置，将R3作为hub端，R1 R2作为spoke端，修改优先级可以实现。中间R1-R4使用静态路由进行互通。
配置如下：

4、 配置动态路由协议。
4.1、R1-R4属于OSPF10的区域0，R3和R5属于OSPF10的区域1，R5和R6属于OSPF20的区域2，使用双进程双向引入连接区域。RIP和OSPF也做重发布。R6和R7属于RIP 100。其中area 2区域修改为nssa区域。

4.2、配置BGP协议，R1-R7为BGP100，R8-R10为BGP200,并且该区域内路由器建立BGP邻居的时候使用全互联的方式。R11属于BGP300。

5、 area 2中不得出现5类LSA
修改area2区域为nssa特殊区域
R5:
ospf 20 router-id 65.5.5.5
area 0.0.0.2
nssa
R6:
ospf 20 router-id 66.6.6.6
area 0.0.0.2
nssa
6、 R11另外创建3个环回接口192.168.1.0 192.168.2.0 192.168.3.0 网段，
#
interface LoopBack0
ip address 11.11.11.11 255.255.255.255
#
interface LoopBack1
ip address 192.168.1.1 255.255.255.0
#
interface LoopBack2
ip address 192.168.2.1 255.255.255.0
#
interface LoopBack3
ip address 192.168.3.1 255.255.255.0
#
7、 网络优化，全网可达
7.1、在R11上使用BGP汇总属性，将192.168.1.0、192.168.2.0、192.168.3.0汇聚为192.168.0.0 255.255.252.0
配置如下：
#
bgp 300
router-id 11.11.11.11
peer 200.102.10.1 as-number 200
#
ipv4-family unicast

network 192.168.1.0
network 192.168.2.0
network 192.168.3.0
peer 200.102.10.1 enable
#
7.2、在R3上面使用OSPF的ABR汇总,将200.102.1.0、200.102.2.0、200.102.3.0汇总为200.102.0.0 255.255.252.0
配置如下：
ospf 10 router-id 53.3.3.3
area 0.0.0.0
abr-summary 200.102.0.0 255.255.252.0
7.3、全网可达
1、先使BGP中AS 200和BGP中AS 300之间互通，因为BGP中AS 200使用了全互联技术，可以使用路由反射器，在R9将R8和R10作为客户端，AS300的路由可以传递到AS200的边界路由器R8。
R8:

#
2、接下来是AS 100和AS 200之间路由传递，因为R8可以通过EBGP接受R7上的路由，我这里在R7上面将RIP学习到的R1-R7的路由引入到BGP的AS 100中，这样BGP的AS 200，就可以通过EBGP方式学习到AS 100内的路由。**
配置如下：
R7：
bgp 100
import-route rip 100
3、下面是AS 100之内的路由传递。因为BGP的IBGP的水平分割机制，导致R7学习到的EBGP路由只能传递给R6，不能继续向内传递，因此我这里使用了路由反射器来使AS 100内的所有路由器学习到R7上面的EBGP路由条目，最终达到全网可达的目标。
在R6上把R7作为反射器客户端，在R5上把R6作为反射器客户端，在R3上把R5作为反射器客户端，在R4上把R3作为反射器客户端。
配置如下：
R6：
bgp 100
peer 7.7.7.7 reflect-client
R5：
bgp 100
peer 6.6.6.6 reflect-client
R3：
bgp 100
peer 5.5.5.5 reflect-client
R4：
bgp 100
peer 2.2.2.2 reflect-client
peer 1.1.1.1 reflect-cilent
peer 3.3.3.3 reflect-cilent
结果测试：
-
测试1.1.1.1 到 11.11.11.11
-
测试2.2.2.2 到 11.11.11.11
