Comment # 9 on bug 1026780 from Marius Tomaschewski

Yes, the config does not match comment #0, set:

VXLAN_REMOTE_IP="239.1.1.42"
VXLAN_REM_CSUM_PARTIAL='yes'

or comment out VXLAN_REM_CSUM_PARTIAL='no' to match the comment #0 setup.

Except of this, there is a bug in ifcfg parsing/conversion, fixed in:

https://github.com/openSUSE/wicked/pull/707

that sends the remote-ip as local-ip causing that the kernel reports
a value out of range :-/

BTW: VXLAN_GPE='yes' is not yet supported and currently ignored.

When you find something else, please provide a debug2 log as described at:

  https://en.opensuse.org/openSUSE:Bugreport_wicked

that is, run:

perl -i -lpe
's{^(WICKED_DEBUG)=.*}{$1=all};s{^(WICKED_LOG_LEVEL)=.*}{$1=debug2}'
/etc/sysconfig/network/config
rcwickedd restart

It will cause to log all the setting sent to/received from kernel.
