Hi Joe, Thanks for your comments. I will surely remove these references from draft. Those were more of typo misses and shouldn¹t have been there in first place.
The idea in this draft is to provide a solution, wherein Vxlan gateway can translate the icmp errors (either PTB or Fragmentation) generated in the underlay and pass it on to the end-point device. Please see inline. Thanks Saumya.
