实验名称：华为OSPF配置演示（1）
实验拓扑：
实验设置：路由器R1 与R2之间配置192.168.12.0/24网段，R2与R3之间配置192.168.23.0/24网段，R3与R4之间配置192.168.34.0/24网段，R4与R5之间配置192.168.45.0/24网段，R1设置loopback10.10.1.1 /24，R2设置loopback10.10.2.2 /24，R3设置loopback10.10.3.3 /24，R4设置loopback10.10.4.4 /24，R5设置loopback10.10.5.5 /24
实验需求：R1，R2，R3，R4，R5之间可以相互ping通，ospf可以同步路由。
