What does VRF Lite mean?

VRF-lite is a feature that enables a service provider to support two or more VPNs, where IP addresses can be overlapped 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.

What is the difference between VRF and VRF Lite?

Full VRF is useful in Service Provider WAN environment where multiple customers are required to be routes across overlapping IP address space. Commonly limited to PE (Provider edge) equipment. VRF lite is generally used in enterprise and Data Center environment.

What is Route target in VRF Lite?

A Route Target (RT) identifies route import and export within VRFs that helps in routing traffic. Every VPN route is associated with one or more than one RT that is exported or imported from other VRFs. A VRF-Lite router is a traffic classifier that is achieved on the CE by defining multiple VRFs.

Is Cisco 3750x Layer 3?

The Cisco 3750-X has been announced as the end-of-sale and end-of-life. Cisco announced the EOS and EOL dates for the Cisco Catalyst 3560-X and 3750-X Series Switches in October, 2015. All the Cisco 3750-X and 3560-X models will be replaced by the new Cisco 3850 and 3650 series.

Why do we use VRF?

Virtual routing and forwarding (VRF) IP technology allows users to configure multiple routing table instances to simultaneously co-exist within the same router. Overlapping IP addresses can be used without conflicting because the multiple routing instances are independent, and can select different outgoing interfaces.

What is VRF in Cisco router?

VRF is an extension of IP routing that provides multiple routing instances. It provides a separate IP routing and forwarding table to each VPN and is used in concert with MP-iBGP (Multi-Protocol internal BGP) between provider equipment (PE) routers to provide Layer 3 MPLS-VPN.

Where do you configure the VLANs used in VRF Lite?

Setting up VRF Lite

  1. Step 1 – Create VLAN segments. Just like its parent, a VRF needs VLAN-based uplink segments for establishing connectivity with the physical network:
  2. Step 2 – Create the VRFs.
  3. Step 3 – Create VRF external interfaces.
  4. Step 4 – Configure BGP.

What is RD value in VRF?

It is a unique number prepended to each route within a VRF to identify it as belonging to that particular VRF or customer. An RD is carried along with a route via MP-BGP when exchanging VPN routes with other PE routers. An RD is 64 bits in length comprising three fields: type (two bytes), administrator, and value.

Where do you configure the VLAN used in VRF Lite?

What is a Cisco VRF?

VRF (Virtual Routing and Forwarding) is a technology that allows having more than one routing table on a single router. The concept of VRFs on routers is similar to VLANs on switches. VRFs are typically used in combination with MPLS VPNs. VRFs without MPLS is called VRF lite.

Does the 3750 support VRF Lite?

full image is c3750-advipservicesk9-mz.122-25.SEC2.bin u need to check if its still supported. in any case it supports vrf lite. I assume in your drawing. 3560’s are really the 3750 where u need vrf lite and the 300Mb is offered over Gigabit Ethernet port?
