Cisco ACI Configuration - Creating VPC and Layer 2 (L2) EPG VLAN Constructs

This video covers creating VPC, L2 EPG VLAN associations via Static Ports (or Path Bindings) as well as using Attachable Entity Profile EPG associations.

Awesome video, even close to 5 years later was helpful

[@bamburaja]

Thanks Jeff for taking time to explain. Really helped a lot. Looking forward to the next one...

[@ManishYadav-rt6eb]

Hi,
I liked all your videos n nicely explained☺️☺️☺️.Thank you very much.
Requesting to make more videos of ACI like L3outs with BGP, Firewall,F5 integration,PBR,microsegmentation.

[@dushyanthpeddi9690]

Thanks for sharing this tutorial. Very helpful content.

[@gastonespinosamachin3092]

excellent and very brief, you are the one

[@elmerdeloso594]

Thanks for creating this tutorial, very helpful...clear & concise. More please.

[@jeffmiller7312]

Thanks for the feedback!

[@mohdikram322]

An excellent demonstration..

[@MultiEthernet]

Perfectly fit to my needs.Thanks a lot!

[@martinpizarro]

Thank you! Very well explained

[@jeffboyer4175]

Thanks Jeff, video was very well done.

[@saadahmadkhan5049]

Thanks for sharing your valuable knowledge. Helped me a lot in own going project

[@andresmenafra914]

Excelent Video!! TY Jeff

[@apacheco2005]

thanks allot. explained very clearly

[@cisconetworkengineer4517]

Thanks Jeff,
one Query-- I see that you selected two interfaces from each leaf ( 1/39 & 1/40 on 201 & 202 leaf switches), wondering why did Port-channel summary show two ports

[@jeffmiller7312]

Hey, it would be two ports per leaf in that scenario. Hopefully that helps. If not, let me know. Thanks Jeff

[@cisconetworkengineer4517]

My bad.. I didn't notice that the port-channel on Nexus also was a VPC .. I got it . Excellent Video Jeff. Thank you so much

[@davidtassie5591]

Wow, no additional information on adding more VLAN-IDs to the vPC. Who uses a single trunked VLAN on a vPC. I'm stuck now.

[@mickyholy]

thanks. very clear and easy to follow

[@TheRhigareda77]

Hey Jeff Awsome vid! I had a question about the layer 2 stuff. Can i apply the same VPC to more than one EPG?

[@jeffmiller7312]

Hey, sorry for the delayed response. Yes, you can use the same VPC on multiple time on the EPG or different EPGs as long as you use a different VLAN encap.

[@vijaysalkar6142]

Thanks Jeff, good video. I have one question....There are three different modes ( Trunk, Access 802.1p & Access-untageged) while configuring VPC in ACI, however in vlan encapsulation field why we cannot enter vlan-range or multiple vlans? Please help to understand how I can extend multiple vlans through ACI VPC link.

[@jeffmiller7312]

Hi Vijay, sorry for the delay here. VLANs are tied to the EPG which is bound to the VPC. So to have multiple VLANs over a VPC you would simply have either multiple EPGs (recommended in network centric) or Multiple VLAN tags tied to the VPC. So it would go EPG --> Static Port Binding (VLAN Tag) to VPC - repeat this step as many VLANs as you need. I also demonstrated in the video a newer way to accomplish this under the AEP as well, but I don't want to confuse thing further for you. :)
Hope this helps and keep trying different methods until it clicks!
Thanks for the question and watching.
Jeff

[@donedeal51]

So is it safe to say that when you expand the L2 bridge domain, you're creating an L2 External Bridge Domain, and when you're expanding the L2 EPG you're creating a L2 Physical Domain?

[@Shriram279-1]

Thanks Jeff, video is good

[@stargategoku]

Thanks Jeff. I have question regarding underlay (MP-BGP, EVPN, ISIS and Multicast) and overlay (VXLAN). don't you need to setup underlay and overlay first before you could use ACI controller? I'm new to NEXUS 9K and ACI datacenter.

[@jeffmiller7312]

Hi, so great question. Cisco ACI is a completely automated modern network fabric. Meaning the configuration of the MP-BGP, VXLAN, IP Addressing, etc... of the underlay is done automatically. With Cisco ACI you move from the need to understand those configurations and only configure the network for the policy or function it should run. Cisco ACI is policy based networking. Example would be segmentation of the application based on application flows or segmentation based on traditional networking (i.e. VLAN, Subnets, etc...).
Hopefully that helps and I will try and make a video of the initial fabric build process in order to see the underlay build.
Thanks for the feedback!
Jeff

[@stargategoku]

Hi Jeff, thanks a lot. apologies for coming back for another questions. i'd like to ask about initial hardware connection between spine and leaf. if i have 2xn9k as spine and4x n9k as leaf, the engineer just plug the cable between spine and leaf and once spine and leaf were connected, apic will be able to see it? thanks again.

[@jeffmiller7312]

Hey, yes the fabric will be auto discovered via LLDP starting with the first APIC connected to the first leaf. I will try to make a video of the initial fabric build as soon as I am able and explain what's going on during the build.

[@aaspirin]

Hi Jeff. After adding a physical domain to an EPG you can click on it and define port encapsulation. Could you plz explain, what does this parameter mean?

[@vetrichelvham]

aaspirin if you’re adding physical domain into your epg. you should choose the static port under epg for where you have the physical devices like computer or any other appliances

[@TheRhigareda77]

also we are planning to leave the SVI on our 5k's for now. will it still work?

[@jeffmiller7312]

Absolutely this will work and is very common during migrations. You will need to make sure you enable flooding on the BD in order to ensure proper functionality.

[@riccardoandreetta9520]

looks like all this "automation" becomes "click here", "click there" for 30 times to have the system configuring "automatically" those 30 commands that previously you were doing by hand

[@aaandrade5]

kinda convoluted explanation, if you ask me...
