Upon creating a port and then updating with multiple fixed IPs per subnet, only one is getting reflected in neutron router config DS.

openstack command used for creating port with multiple fixed-ips:

neutron port-create ext-net --fixed-ip subnet_id=d8c6125a-8d1a-4802-8bfe-d287776c8b41,ip_address=12.12.12.8 --fixed-ip subnet_id=d8c6125a-8d1a-4802-8bfe-d287776c8b41,ip_address=12.12.12.9
