Solved 300-101 VRF Lite episode

---

Hello ITPro! I had a follow up question regarding the CCNP Route 300-101 "VRF Lite" episode. I am completely new to VRF, but followed along with a router in my lab. The only thing that wasn't clear was how you planned to get each customer (customer1 and customer2 in the demo) to connect to the ISP WAN network..? At the end of the demo you had 3 different routing tables, one for each customer and the native table to the router.

How would traffic from customer1 get routed out to the ISP's WAN connection? Or would you have to pull an interface into the same VRF with a customer to make that happen?

@Adam-Tyler,

In this instance, you don't have to worry about it the ISP does. when using VRF lite, you'll have to get mulitple IPs from the ISP to make it work. The ISP will then have their routing table for the addresses they will provide to the traffic that arrives at their edge and will be able to route traffic exiting from customer 1 back to customer 1 etc.

When working at the edge of your networks, you have to provide connectivity and path to the edge. The ISP will be able to route them through their network back to you.

With no other responses, I've marked this as solved.
