Can someone explain what is a VRF (for beginners)

[Deepak Kumar · Accepted solution]

Hi,

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.

In addition to that, it is mostly suitable for larger networks, for instance, service providers or larger enterprise networks.

"In addition to that, it is mostly suitable for larger networks . . ."

Unsure "suitable" would be best word choice as much would depend on network requirements rather than network size, I suspect.

For example, when I worked for Comcast supporting their Enterprise network, with about 5,000 network routers and switches supporting about 100,000 users, we didn't need nor use VRFs.

You are right, it’s dependent on requirements.
