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, called 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 it is running the IP services or advanced IP services feature set.
Multi-VRF CE allows a service provider to support two or more VPNs with overlapping IP addresses.
