[c-nsp] BGP-EVPN vs Traditional Nexus 7k/5k Design

[Gustav Ulander]

Hello.
Lots of if and buts in the BGP E-VPN and VXLAN solution including some not so nice bugs. 
Documentation isn't really clear on some of the pitfalls either. I would suggest a heavy testing period more so than usual perhaps. 
Since you are running L3 on all those 1u boxes make sure that you understand where you land in the scalability documents. Some knobs bring scalability way down especially if you are running it with the older 9300 generation switches since they are Broadcom based. 
Newer generation 9200 and 9300 is better but there is still a couple of pitfalls to step into.

Ämne: [c-nsp] BGP-EVPN vs Traditional Nexus 7k/5k Design

Hi Gentlemen,

We are planning to upgrade our data centers which were built on cisco'
traditional design at that time i.e nexus7Ks as core and nexus5Ks and 2Ks as distribution and access layer (TOR). In this design, 7Ks run layer-3 and extend layer2 via VPC down to 5Ks. We have the multi-tenant environment (VDCs and VRFs) and host customer's critical services

For the upgrade, we are exploring BGP-EVPN with VXLAN option? can someone please give me the pros and cons when compare with traditional 7ks/5ks vpc design? I read about cisco's bgp-evpn design but not sure yet what is the real value. are there real benefits or its just marketing fluff to sell nexus 9Ks and part of SDN buzz.

cisco also offer ACI and we may want to try it in green field deployment but don't think it mature enough and ready for us to migrate the critical customer's service over it now.

Regards
