Subject: vxlan_asymmetric.sh test failed every time
Date: Tue, 13 Oct 2020 12:39:43 +0800 [thread overview]
Message-ID: <20201013043943.GL2531@dhcp-12-153.nay.redhat.com> (raw)
Hi Ido,
When run vxlan_asymmetric.sh on RHEL8, It failed every time. I though that
it may failed because the kernel version is too old. But today I tried with
latest kernel, it still failed. Would you please help check if I missed
any configuration?
