The following figure is an example of the devices connecting to each other in the Multi-area SPB network.
Note
The example applies to VSP 7400 Series only.
The following sections display an example to configure the two boundary nodes in the Multi-area SPB network (BG1 and BG2), to enable remote Intermediate-System-to-Intermediate-System (IS-IS), and to configure the layer 2 and layer 3 unicast redistribution.
Note
You must first configure basic SPBM and IS-IS infrastructure. For more information, see SPBM configuration examples.
