RVI support for private VLANs

You can configure a routed VLAN interface (RVI) on a switch to handle the Layer 3 traffic of inter-secondary VLANs (community VLANs and isolated VLANs) in a private VLAN (PVLAN). By using an RVI to handle the routing within the PVLAN, you eliminate the need for an external router with a promiscuous port connection to perform this function. One RVI serves the entire PVLAN domain regardless of whether the domain consists of one or more switches. After you configure the RVI, Layer 3 packets received by the secondary VLAN interfaces are mapped to and routed by the RVI.
