Configuring Multi-VRF CE

Virtual Private Networks (VPNs) provide a secure way for customers to share bandwidth over an
ISP-backbone network. A VPN is a collection of sites sharing a common routing table. A customer site
is connected to the service-provider network by one or more interfaces, and the service provider
associates each interface with a VPN routing table known as a VPN routing/forwarding (VRF) table.
The switch supports multiple VPN routing/forwarding (multi-VRF) instances in customer-edge (CE)
devices (multi-VRF CE) when the switch is running the IP services feature set. A service provider uses
multi-VRF CE allows to support two or more VPNs with overlapping IP addresses.
The switch does not use Multiprotocol Label Switching (MPLS) to support VPNs. For information about
Note
MPLS VRF, see the Cisco IOS Switching Services Configuration Guide, Release 12.2.
