[Bug 1464361] Re: Support for multiple gateways in Neutron subnets
For now I don't think we are going to go forward with this because it's
a very invasive change and there isn't a really strong demand for it.
Let's revisit this if necessary after the routed networks and other
model changes happen during mitaka that are designed to help with large
operator use cases like this.

Title:
Support for multiple gateways in Neutron subnets
Status in neutron:
Won't Fix
Bug description:
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.
