VrfApp Service

This chapter describes the DCNM web services' API methods for the VrfApp service.

Information About VrfApp Service

The Layer 3 functionality in a VDC can be further virtualized into multiple routing domains using virtual routing and forwarding (VRF) instances. A separate routing and forwarding table is maintained for each VRF. A Layer 3 interface (logical or physical) in a VDC can belong to exactly one VRF. A VRF is local to a VDC and each VDC can contain multiple VRFs. By default, each VDC will contain a VRF. By default, all Layer 3 interfaces belong to the default VRF. In addition, for each VDC, a management VRF is created automatically.

Cisco NX-OS supports a VRF-lite implementation. VRF-lite enables a service provider to support two or more VPNs, where the IP addresses can overlap among the VPNs. VRF-lite uses input interfaces to distinguish routes for different VPNs and forms virtual packet-forwarding tables by associating one or more Layer 3 interfaces with each VRF. Interfaces in a VRF can be either physical, such as Ethernet ports, or logical, such as a VLAN SVI. A Layer 3 interface cannot belong to more than one VRF.

With VRF-lite, multiple customers can share one customer edge (CE), and only one physical link is used between the CE and the provider edge (PE). The shared CE maintains separate VRF tables for each customer and routes packets for each customer based on its own routing table. VRF-lite extends limited PE functionality to a CE device, giving it the ability to maintain separate VRF tables to extend the privacy and security of a VPN to the branch office.
