CHAPTER 29 VIRTUAL ROUTING AND FORWARDING
This chapter covers the Virtual Routing and Forwarding Customer Edge (VRF-
CE) configuration on the OmniAccess 5740 USG.
VRF-CE is a feature that enables a service provider to support two or more VPNs,
where IP addresses can be overlapped among the VPNs. VRF-CE 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. A
Layer 3 interface can belong to only one VRF at any time. Interfaces in a VRF can
be either physical or logical such as VLANs.
This chapter includes the following sections:
• “VRF-CE Overview”
• “VRF-CE Configuration”
The “VRF-CE Overview” section provides an insight on the concept of VRF-CE.
This information serves as an educational overview. You can skip this section and
move onto the VRF-CE configuration directly.
