Very well explained Rafik, Was searching for a good one from Dell (VxLAN). So the tricky BGP part is if you forgot to disable BGP ipv4 routing , it will overcome the OSPF routing in routing table since the BGP administrative distance is lower then OSPF. Is that the reason I believe , Correct ??
Dumb question: why all the vxlan jazz, to get VLAN 100 from one rack to the other? Why can’t spines and leafs trunk vlans? Why the extra encapsulation and routing?
there is never a dumb question , the reason why, without VXLANs, your physical Network Switches need to be aware about all VLANs in order to trunk, otherwise packets are going to be discarded .. with the concept of VXLAN, now we can have the Overlay, for example VMware NSX, creating VXLANs tunnels on top of the Physical Network without the need to create every new VXLAN on the Physical Switch, and also to overcome the limitation of only 4K Vlans .. I hope this helps :)
Thanks for the Awesome Session , Please make more videos like this.
Great work! Nicely done.
Well done, Rafik.
Great video, thank you.
useful thx

I wish you would have also shown SPINE switch configuration for static configuration --
Which OS version are you running? thanks
Hi Rafic,
Could you make a vedio on VxLAN routing.
