    Abstract: In general, techniques for facilitating a distributed network (L3) subnet by which multiple independent control planes of network devices connected to physically separate L2 networks provide L2 reachability to/from a single L3 subnet. In some examples, a shared L2 network physically situated to connect a plurality of physically separate L2 networks “stitches” the L2 networks together within the respective, independent control planes of switches such that the control planes bridge L2 traffic for a single bridge domain for the separate L2 networks to the shared L2 network and visa-versa. Each of the independent control planes may be configured with a virtual IRB instance associated with the bridge domain and with a common network subnet. Each of the virtual IRBs provides a functionally similar routing interface for the single bridge domain for the separate L2 networks and allows the shared network subnet to be distributed among the independent control planes.

    Abstract translation: 通常,用于促进分布式网络(L3)子网的技术通过其连接到物理上分离的L2网络的网络设备的多个独立控制平面提供到/来自单个L3子网的L2可达性。 在一些示例中,物理地定位以连接多个物理上分离的L2网络的共享L2网络将L2网络在交换机的相应的独立控制平面内“联结”在一起,使得控制平面桥接用于单桥域的L2业务 将L2网络分离到共享的L2网络,反之亦然。 每个独立控制平面可以配置有与网桥域相关联的虚拟IRB实例以及公共网络子网。 每个虚拟IRB为单独的L2网络的单桥域提供功能相似的路由接口,并允许共享网络子网在独立控制平面之间分布。
