Hello,
I also meet some problem when execute LTP geneve testing. Hope for your help or advices.
This case builds geneve tunnel between server and client firstly, then execute netstress test. The geneve tunnel contains ipv4 and ipv6 two categories.
The case works fine under ipv4, but ipv6 failed that the server and client can’t ping each other.
I have checked the module and driver, both of them are OK. The command of building tunnel executes correctly. I also check the route, it is fine.
Does anyone have any advices?
The server and client are connected directly, without switch.
