I'm reading the Design Guide - NSX-T 3.1 Multi-Locations-v1.1.pdf and I see that an RTEP MTU greater or equal at 1700 is suggested.
L2 Stretched communication is:
1) From ESXi to Edge Node
2) Edge Node to Edge Node (using RTEP*)
3) Edge Node to ESXi
In point 1) there is a GENEVE incapsulation and decapsulation?
Or the GENEVE traffic incapsulated by the first TEP is incapsulated a second time by the RTEP?
My simple question is: why MTU>=1700 and not MTU>=1600 for the RTEP?
