Hi.
I'm working with OVS 2.13.2&OVN20.02,I want to use IPv6 tunnel-encap and
here is my configure step:
1、create ovs bridge and tunnel port（vtep）
2、bring up vtep and get vtep's IPv6 addr(ovn-encap-ip)
3、set ovs's external_id:ovn-encap-ip to vtep's IPv6 addr
[root@node]# ovs-vsctl list op

when I set OVS's tunnel type(ovn-encap-type) to VXLAN or geneve,the tunnel
works fun;but when i change OVS's tunnel type to STT,I got following error:
ovs-vswitchd.log:

Does OVS 2.13.2 support STT IPv6 encap?
