VRF-Lite – Full review of VRF-Lite, how it differs from VRF, and configuration / verification commands for exam day!

VRF-Lite is quite literally a light weight version of VRF Instances, where instead of using VRF to accomplish complex configurations, it simply segregates IP Routing / Instructs Physical Interfaces to use the specific VRF Route Table needed to function. Quick guide to configuring the above Topology with VRF-Lite First you will want to use "ip … Continue reading VRF-Lite – Full review of VRF-Lite, how it differs from VRF, and configuration / verification commands for exam day!

VPN: VRF-Lite review of behaviors, EVN Fundamentals, configuration explained, no labbing due to constraints even on 15.x IOS!

  As I will not be doing a DEEP Dive or review of VRF-Lite outside of reviewing my own post on its configuration, I figured I would put the highlights of my VRF-Lite post here in terms of configuration. This way we can both get an overview of VRF-Lite, and how it compares to EVN, … Continue reading VPN: VRF-Lite review of behaviors, EVN Fundamentals, configuration explained, no labbing due to constraints even on 15.x IOS!

VRF-Lite: Complete configuration and explanation of behaviors, OSPF and EIGRP demonstration and how they work (or why the don’t work)

To note I used the same color I have previously for IPSec VPN tunnels, however that color is more just one of the few colors not reserved for protocols (as I generally use blue for OSPF, red for RIP, and orange for EIGRP), so this time green is for VRF-Lite. So I wanted to pull … Continue reading VRF-Lite: Complete configuration and explanation of behaviors, OSPF and EIGRP demonstration and how they work (or why the don’t work)

VRF (Virtual Routing and Forwarding) and VRF-Lite theory and initial lab setup (Your CCNA Router on a Stick refresher!)

First I would like to draw the line in the sand between VRF, and VRF-Lite. VRF was created mainly for MPLS VPNs using BGP, so it is beyond the scope of the CCNP R/S, however Lite version uses the same theory and commands (mostly) VRF-Lite is for smaller scale deployment, but uses the same theory … Continue reading VRF (Virtual Routing and Forwarding) and VRF-Lite theory and initial lab setup (Your CCNA Router on a Stick refresher!)
