EVPN in Data Center | EVPN - VxLAN | Three tier Vs Spine & leaf

[@abhisheksa6635]

We talked about various features in this EVPN need for DCI, mostly what I could capture is again back to BGP control plane to prevent storm in the data plane, rest of the communities discussed along with IRB usage and how the multihoming scenario is used, kindly help us with labs taking the legacy DC vs EVPN DC.

Hi i have a one small question, PE-PE MAC exchange happen in control plane but wat about PE-customer(hosts). Host will still send broadcast ARP to PE and PE will send to other PEs n then intended customer will reply? HOW PE --CE flood n learn is avoided in EVPN?

[@Ten-Dot-One]

PE CE is data plane learning via ARP PE to PE control plane learning.

@@Ten-Dot-One how does it help ? Pe--ce is data plane learning then arp broadcast sent to all pes? Same as traditional thing. Or pe has some mechanism to look at dest ip address and reply to hosts?
