The following figure is an example of the devices connecting to each other in the Multi-area SPB network.
Note
The example applies to 5520 Series, 5720 Series, 7520 Series, and 7720 Series.
The following sections display an example to configure 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.
