MicroNugget: What is VRF Lite?

In this video, Anthony Sequeira covers using VRF Lite for segmenting and partitioning traffic at Layer 3. Segmenting traffic with virtual routing and forwarding tables in MPLS environments is one thing, but what about when you're not using MPLS? Anthony configures VRF Lite before your eyes.

VRF Lite makes it possible to take particular traffic and give it its own routing tables in the infrastructure, even when you're working in an environment without MPLS. That sort of Layer 3 segmentation can help keep a network environment with high risk devices secure. First hand, Anthony demonstrates how to configure your devices' custom routing tables. First, he creates the virtual routing and forwarding tables that'll get used. Then, he goes directly into the interfaces to have them participate in the VRFs. He establishes the IP addresses and maps the path for each VRF. He wraps up by configuring the addresses that go out to the internet, and then places each interface into their respective VRF environment. By following along, you'll learn how to replace a global routing table with custom made virtual routing tables and be one step closer to being prepared for the CCIE Routing and Switching.

All others confused me. Thank you for simplifying the VRF concept :) Nice work & good example chosen,

[franciscotorrecillas]

Great explanation, very clear and concise

[Gooseycoyne]

This is a fantastic video. I could never find a proper source. I was always under the illusion that the connected routers also had to be part of the vrf ospf process but they just run a routing protocol like normal. Its only local to the router performing VRF. Thanks for clearing that up.

Very good overview. We are implementing but with dell force ten hardware.

[nishantkumar-qnmu]

superb to start of learning VRF basics

[phkh]

Thank you very much favor the sacrifice share knowledge.
Let all good things in the world. Wish you are happy

Hi sir, Next when you make video please keep configuration in middle page, We couldnt seee when mouse on the screen it is covered with scroll

[ДунканМаклауд-тл]

Can't understand why we get debug message like:
" % Interface IPv4 disabled and address removed due to DISABLING!!! VRF..."

Why we get "DISABLING" message, if we ENABLING VRF using this command ?!!!

[TVlight]

Layer 3 segment without mpls by giving interfaces and different routing tables

[nandu]

can we configure Sub interfaces and assign VRF to it..

[jagageralla]

why not use access lists on the switch to do the same thing?

[rami_rasikh]

how (LabCLIENTS) & (CLIENTS) can reach their resources while they pass through Ethernet1/0 & Ethernet1/1 ??  which they are a passive interfaces.

Younger Anthony sounds like a Cali kid.
