I have configured in a lab logical switch, distributed router, distributed firewall and everything is work fine.
But then I thing about real live environment I am a little bit confused about VTEPs and VXLAN. I understand that VTEP encapsulate the original frame with outer header with VXLAN IP and MAC to deliver the original frame over L3 transport network. But I don't understand requirements for physical network. Does every switch, for example cisco 2900 or cisco 3750 will understand vxlan encapsulated frames from VTEp adapters? Do I need to do some extra configuration on physical switch except of MTU 1600? Then I google I always see nexus 9000 switch which support VXLAN and has VTEP.
So my question is: can my logical switch distributed over physical environment with catalyst 2900, 3700 and etc series switch and routers like 2900 or ASR/ISR routers? will my "non-data center equipment" understand vxlan encapsulated frames or I need only NEXUS series switch to do this?
Thank you very much )
