I had a close look at the failure and proposed the following WIP patch[1] to address this use-case. However, when playing with multi subnets in the same network, I'm seeing many issues. Basically, Netvirt needs some additional changes to support multiple subnets in the same network. So the use-case is more like an enhancement/RFE than a bug fix and will take sometime to address it properly. [1] https://git.opendaylight.org/gerrit/#/c/64113/
This is currently not supported in NetVirt. Multiple IPv6 subnets in a given network is not a widely used feature as far as I can tell, so I am closing this bug for now. Will open again if we have concrete customer demand.
