Inter-VSN Routing with SPBM Configuration Example

The following figure shows a sample Inter-VSN deployment.

Inter-VSN routing configuration

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 SwitchG.
