The ipv6 router BP (https://blueprints.launchpad.net/neutron/+spec/ipv6-router) added a new L3 agent config called ipv6_gateway wherein an admin can configure the IPv6 LLA of the upstream physical router, so that the neutron virtual router has a default V6 gateway route to the upstream router.
This change aims to make this exact change by updating the router_update API so that the neutron router-gateway-set CLI will now have a new option to set an ipv6_gateway.

This solution is however not scalable when there are multiple external routers per L3 agent. /review. openstack. org/#/c/ 156283/ 42/etc/ l3_agent. ini

It is better to move this config to the CLI.
