Nexus vPC | Configuration on Real Cisco Nexus Switches
In this video, we configure vPC on real Cisco Nexus 9000 switches.
Starting with the basics, and moving through to a deep dive, this real lab shows how Network Engineers can configure peer-link, keep alive link, member ports, orphan ports, and peer gateway.
Useful for CCNA Data Center, CCNP Data Center, and CCIE Data Center.
the pitfall of routing over #vPC, and how to avoid it, using layer-3 peer-router
This video is particularly helpful to network engineers working with vPC in production.

How VRFs Work (VRF Lite) | VRFs Part 1
VRFs, or Virtual Routing and Forwarding, are virtual routing tables. They enable separation of one part of the network from another.
There could be many reasons to do this. It could be for security, to separate the inside network from the DMZ. Or, it could be to separate BU's, or separate customers from each other.
This video explains VRF basics, what they are used for, when they are used, and how they work.
This includes two labs you can follow along with.
The first lab starts at the beginning and shows basic VRF configuration to separate two customers.
The second lab shows how you can use VRFs to force traffic through a firewall for security purposes.
You can download the labs, and practice on your own if you want (Patreon).

Dynamic Routing with VRFs | BGP, OSPF, and EIGRP | VRFs Part 2
VRFs, or Virtual Routing and Forwarding, are virtual routing tables. They enable separation of one part of the network from another.
We follow on from where part 2 left off. Here, we look at using VRF's with IGPs to enable dynamic routing.
Join me to see how we can configure a network with VRF's, as well as EIGRP, OSPF, and BGP. You'll also get to see more on how address-families work.
This includes two configuration labs you can follow along with.
(0:14) The first lab will walk you through how OSPF and EIGRP are used when connecting customer routers.
(1:46) The second lab dives deeper by looking at how we can integrate BGP, such as when we connect a WAN router that we don't manage

Route Target Import and Export | Extending VRF's Across the Core | VRFs Part 3
It's great that we can segregate our customers into virtual routing tables using VRF's. But how do we enable this across many routers?
It would be difficult to manually configure VRFs on each router. Imagine the time and effort spent on this task!
Instead, we can use MP-BGP (Multiprotocol BGP) to tag each route as they're shared. These tags are called route-targets. Now routes can be exported out of a VRF on one router, shared with another router through BGP, and then imported into the correct VRF.
While we're on the topic, how do routes stay unique in the BGP database? VRF's can also be given a tag, called a route-distinguisher, which accomplishes this task.
In this video, we'll see how to configure route distinguishers and route targets to keep customer routes unique. We'll also see how to share routes across a core network. Maybe we'll even see a little introduction to MPLS!

Leak Routes Between We've been very successful in keeping customer routes separate with VRF's. We've even extended this across the core using route-targets, route-distinguishers, and MPLS.
What would happen now if we wanted to share some of our routes with our customers?
This is called route leaking, which we can achieve once again with MP-BGP.
There are a few challenges along the way. What if we want to share all routes in a VRF? What if we want to be selective? And how do we prevent customers from advertising rogue routes?
In this video, we'll see how to configure route leaking and export maps to to share routes between VRFs.
