Setup
I have two transport nodes and one edge VM. The transport nodes vteps are 172.16.1.10 and 172.16.1.11 and The edge node vm vtep is 172.16.1.15.
Issue
Jumbo pings between transport nodes vteps works, whereas between transport node and edge vm fails.
Jumbo ping dump between transport nodes vteps:-

Probable Root Cause
I observed Dropped No Memory counters incremented during jumbo frame pings. Any inputs in resolving this issue would be of great help.
