Public bug reported:
Currently, the subnets in Neutron only support one gateway. For provider
networks in large data centers, quite often, the architecture is such a
way that multiple gateways are configured for the subnets. These
multiple gateways are typically spread across backplanes so that the
production traffic can be load-balanced between backplanes.
This is just my use case for supporting multiple gateways, but other
folks might have more use cases as well.
I want to open up a discussion on this topic and figure out the best way
to handle this. Should this be done in a same way as dns-nameserver,
with a separate table with two columns: gateway_ip, subnet_id.
