Description Thadeu Lima de Souza Cascardo 2016-11-29 18:44:02 UTC
If one configures multiple VXLAN tunnels on the same port, with different flags (like GBP), OVS won't be able to handle that. It should refuse such configurations.

See RFC/patch and discussion upstream.

I have submitted a new patch, but I think this patch was not needed to begin with. I've asked upstream to also comment on this. Patch is here:

Comment 5 Eelco Chaudron 2017-07-25 12:35:10 UTC
Need to do some more testing to see what Linux support in the datapath and re-send (or ack) patch.

Comment 6 Eelco Chaudron 2018-02-09 14:45:26 UTC
Submitted v2 patch after confirming current implementation does not support concomitant tunnels.
