HCIP作业

为了在eNSP中实现图中的网络结构，并确保五台路由器的环回地址可以相互访问，我们需要配置各路由器的接口IP地址、OSPF和BGP等路由协议。以下是详细的配置步骤和命令：

1. 配置路由器AR1

system-view

sysname AR1

interface GigabitEthernet0/0/0

 ip address 12.0.0.1 255.255.255.0

interface Loopback0

 ip address 172.16.1.1 255.255.255.255

 bgp 100

 router-id 172.16.1.1

 peer 12.0.0.2 as-number 200

2. 配置路由器AR2

system-view

sysname AR2

interface GigabitEthernet0/0/0

 ip address 23.0.0.1 255.255.255.0

interface GigabitEthernet0/0/1

 ip address 12.0.0.2 255.255.255.0

interface Loopback0

 ip address 172.16.2.1 255.255.255.255

 ospf

 router-id 2.2.2.2

 area 0

 network 23.0.0.0 0.0.0.255

 network 12.0.0.0 0.0.0.255

3. 配置路由器AR3

system-view

sysname AR3

interface GigabitEthernet0/0/0

 ip address 23.0.0.2 255.255.255.0

interface GigabitEthernet0/0/1

 ip address 34.0.0.1 255.255.255.0

interface Loopback0

 ip address 172.16.3.1 255.255.255.255

 ospf

 router-id 3.3.3.3

 area 0

 network 23.0.0.0 0.0.0.255

 network 34.0.0.0 0.0.0.255

4. 配置路由器AR4

system-view

sysname AR4

interface GigabitEthernet0/0/0

 ip address 34.0.0.2 255.255.255.0

interface GigabitEthernet0/0/1

 ip address 45.0.0.1 255.255.255.0

interface Loopback0

 ip address 172.16.4.1 255.255.255.255

 ospf

 router-id 4.4.4.4

 area 0

 network 34.0.0.0 0.0.0.255

 network 45.0.0.0 0.0.0.255

5. 配置路由器AR5

system-view

sysname AR5

interface GigabitEthernet0/0/0

 ip address 45.0.0.2 255.255.255.0

interface Loopback0

 ip address 172.16.5.1 255.255.255.255

 bgp 300

 router-id 172.16.5.1

 peer 45.0.0.1 as-number 400

注意事项

确保每台路由器的接口IP地址与图中一致。

OSPF和BGP的配置需要根据实际的AS号和网络情况进行调整。

环回地址用于模拟路由器的标识符，确保每台路由器的环回地址唯一且可访问。
