Cisco Cisco IOS Software Release 12.0(22)S

This document describes the Simple Network Management Protocol (SNMP) agent support in Cisco IOS 
for Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) management, as 
implemented in the draft MPLS/BGP Virtual Private Network Management Information Base Using 
SMIv2 (draft-ietf-ppvpn-mpls-vpn-mib-03.txt).

The MPLS VPN technology allows service providers to offer intranet and extranet VPN services that 
directly connect their customers' remote offices to a public network with the same security and service 
levels that a private network offers. Each VPN is associated with one or more VPN routing/forwarding 
instances (VRFs). A VRF is created for each VPN defined on a router and contains most of the 
information needed to manage and monitor MPLS VPNs: an IP routing table, a derived Cisco Express 
Forwarding (CEF) table, a set of interfaces that use this forwarding table, and a set of rules and routing 
protocol parameters that control the information that is included into the routing table. The 
Provider-Provisioned VPN (PPVPN)-MPLS-VPN MIB provides access to this VRF information, as well 
as interfaces included in the VRF, and other configuration and monitoring information.
