Understanding EVPN IRB and Routing Types

In this part of the EVPN-VXLAN series, we will look at the different EVPN (Ethernet Virtual Private Network) routing types. Specifically asymmetrical routing and symmetrical routing. This is an advanced topic but as always the basics will will be covered first such as:
- What is a MAC-VRF
- What is an IP-VRF
- How do we route between VNI's
- What is asymmetrical routing, the packet journey and its limitations
- What is symmetrical routing and its packet journey.

These are the best videos on EVPN VXLAN on the internet! Thank you so much.

That’s so kind of you. Thanks very much for amazing feedback

50:30 in outer header dest MAC should be Leaf 3 and Src MAC should be spine 1 you mixed up the fields :)

@@dota2tournamentss haha as Homer Simpson would say “doh”. This is why I don’t like ppts 😂 Thanks for the support 👍

Thanks for these amazing videos and I hope more engineers will come here and learn more.

I hope so too! Thanks for your support 👍

Good stuff and great work breaking this down to bite size pieces as this gets rather complicated fast.

[@Netcademy]

Thanks very much! Honestly this topic was a rather advanced and useful had to go through many different sources of info to get all the clear, easy & digestible facts together. 👍

[@Peace_Of_Mind789]

Thanks a lot. One of the best explanation indeed....

[@Netcademy]

You’re very welcome and thanks for the great feedback

In symmetric routing case, how does the leaf1, 5010 mac-vrf IRB gateway determine that it need to transit to 'leaf2" specifically?

[@flyingpan2639]

Could you plz explaine anycast gateway too?
for example, I wonder what leaf switch that the actual gw ip address configured?
and if that leaf was down, what happens to the hosts to get another networks that needs to routing?

[@Netcademy]

Please check out part 2 of this series where Anycast Gateway is explained 👍
If a leaf device had the gateway addresses (anycast) this would be ERB model. Hopefully a server attached to it is multihomed as if the leaf goes down and that server only has 1 connection for networking; then that server is in deep trouble till the leaf comes back up. But in a multi homed environment using ERB, each leaf device would have the same anycast gateway virtual ip and MAC address. So if a lead were to fail and if a server was multi homed, then it would still see that anycast ip address but now with only one valid next hop, not two. Hope that helps

I would just pronounce it Vee Ar Ef and not VERF

Haha yes - got to remember to KISS :)
