Comment 11 for bug 1905295

Thanks Bence for the clarification.
Regarding #10, you need active-active router interfaces in neutron. You also would like to have multiple (external) networks ("external" here means "outgoing" networks for a cloud).
What I am not sure is whether multiple routers on a single network (for "outgoing") does not satisfy your need.

The reason I asked this is because I previously heard a bit different need that operators would like to make external routes redundant (i.e. a single neutron router would like to have multiple external connection). This is a similar need, but your requirements sounds different from two points: active-active neutron router instances AND multiple external networks.
