Older versions of ovs-vsctl may not report the error, but you will see it on
the ovs-vswitchd log file.
Implementing IPv6 support for tunnels is not trivial. You need to add
support in both user space and kernel datapath, and the netlink protocol
between the two. This involves changes in many files.
Thanks, i see. =(
Okay i'm try to patch some files on userspace and check. If i get
getaddrinfo on address without dns lookup - does it acceptable
solution? After that i can simplify switch code based on address
family..
It's not as simple as using getaddrinfo(). You need to add support for
IPv6 addresses in tunnel related data structures for flows. Please take
a look at datapath/flow.h you'll see struct ovs_key_ipv4_tunnel. You
would need an IPv6 equivalent. Same with netlink flow key. In
include/linux/openvswitch.h you have OVS_TUNNEL_KEY_ATTR_IPV4_SRC and
OVS_TUNNEL_KEY_ATTR_IPV4_DST. You need the IPv6 equivalents. Then you
need to add the accompanying logic.
I saw you had a similar question for Geneve. I believe the same applies
there.
