- Let's say that we're a service provider
and we need to maintain separate routing tables
for each of our clients.
Does that mean that we need to get a physical router
and dedicate it to each client just to keep
their routing information isolated from one another?
Well, not necessarily.
Instead, we might use a technology called virtual routing
and forwarding, or VRF for short.
And in this section, we're going to discuss
a specific type of VRF called VRF-lite.
First, we'll talk about the theory,
and then, we'll see how it's configured.
