You must configure the required SPBM IS-IS infrastructure.
You must configure a VRF and IP VPN instance on the switch. For more information about how to configure a VRF, see VRF Lite configuration using Enterprise Device Manager.
You must create the Customer VLANs and add slots/ports.
After you have configured the SPBM infrastructure, you can enable SPBM Layer 3 Virtual Services Network (VSN) to advertise IPv4 routes across the SPBM network from one VRF to another using the following procedure.
SPBM Layer 3 VSN uses IS-IS to exchange the routing information for each VRF. In a non-default VRF, just like in the Global Router, the routes are not redistributed into IS-IS automatically. To advertise the VRF routes, you must explicitly redistribute a protocol into IS-IS, within the context of a VRF. Routing between VRFs is also possible by using redistribution policies and injecting routes from the other protocols. This procedure includes a route policy. To configure IS-IS redistribution, see Configure IPv4 IS-IS redistribution.
