I believe it is common for people like to research network technology but would not like to purchase expansive devices to stack them at home. To make myself more understanding how ospf operate in JunOS environment, I started to set up a small topology to configure OSPF with logical router feature.

JunOS OSPF配置实践
本文介绍了一位网络技术爱好者如何在虚拟环境中设置并配置Juniper JunOS路由器以实现OSPF区域10内的互联互通。通过定义逻辑路由器R1和R2,并在它们之间配置OSPF协议,作者成功建立了稳定的邻居关系并验证了路由数据库的有效性。
