Works mostly the same as a VRF in MPLS/VPN networks, labels are replaced with VNI numbers and VPNv4/v6 routes become Type-5's. Assigning RD + RT is still the same :) And symmetric / asymmetric is the difference between "per table label" or "per prefix label", with the latter the remote PE doesn't do the route lookup, same with the EVPN asymmetric then it only does the switching lookup (except for VTEP de-capsulation but let's ignore that).

Is there a similar tutorial on MPLS/VPN just to understand and compare with this EVPN?

[@ttech1280]

This will be one to watch a few times.

Yep. I'm right there with you. I want to get a lab stood up and work through the forwarding tables to make sure I really grasp this. /Ethan

[@gurbirsingh2850]

Brilliant questions, awesome tutorial if you want to understand L2 L3 VNIs

[@techevangelist8373]

while going through this, I had the same doubt about why do we need an L3 VNI

[@achrafharkati3900]

Any idea what tool is being used for drawing ?

[@PacketPushersNetwork]

IIRC, Tony is using Notability. /Ethan
