Hello
Again, I ask the question.
I did a lab configuration on the Cisco provided site, and there was no abnormality in the ping test between the hosts.
However, if you perform a ping test on the leaf device, a time out occurs.
Q. The figure above shows a ping from the LEAF-1 device to HOST-2 via Wireshark.
1. ping from LEAF-1 to HOST-2.
2. ping request from LEAF-2 to HOST-2.
3. Ping reply from HOST-2 to LEAF-1
4. LEAF-2 nve1 gateway pings back to HOST-2. (I guess that's where the loop happens)
5. SPINE does not receive a response to the ping request and the TTL exceeds 255. (no response found!)
I tried changing the nve1 gateway IP address, but it was the same symptom.
The conclusion is that the ping test failed on the LEAF equipment, and the above assumption is just my guess.
I think i should have a ping from the device to the host.
* i collect and deliver config and wireshark files. to facilitate the analysis, only Leaf-1,2 and Spine-1 were operated and collected.
This is the procedure I did after Wireshark was up and running.
1. Ping test from Host-1 to Host-2 << no abnormality.
2. Ping test from Leaf-1 to Host-2 << ping timeout.
Best Regards,
