The following figure shows a sample Inter-VSN deployment.
The following sections show the steps required to configure the Inter-VSN parameters in this example. You must first configure basic SPBM and IS-IS infrastructure. For more information, see: SPBM Configuration Examples.
Note that the IP interfaces are configured where the routing instance exists, namely, on Switch-20 (BCB C).
