Cisco Cisco IOS Software Release 12.0(22)S

This document describes the MPLS VPN ID feature and includes the following sections:

Using Multiprotocol Label Switching (MPLS) VPN ID you can identify virtual private networks (VPNs) 
by a VPN identification number, as described in RFC 2685. This implementation of the MPLS VPN ID 
feature is used for identifying a VPN. The MPLS VPN ID feature is not used to control the distribution 
of routing information or to associate IP addresses with MPLS VPN ID numbers in routing updates. 

Multiple VPNs can be configured in a router. You can use a VPN name (a unique ASCII string) to 
reference a specific VPN configured in the router. Alternately, you can use a VPN ID to identify a 
particular VPN in the router. The VPN ID follows a standard specification (RFC 2685). To ensure that 
the VPN has a consistent VPN ID, assign the same VPN ID to all the routers in the service provider 
network that services that VPN.

You can use several applications to manage VPNs by VPN ID. For more details on how server 
applications use the VPN ID, refer to the
