default gateway in config_db.json for frr

[Justin Hannah]

I have a default gateway that goes to a carrier I am connecting to via VLAN.  Is there a supported method to put a default gateway on non-mgmt interface in config_db.json besides using FRR split ( "docker_routing_config_mode": "split" ) or some other hack.

This method does not seem to work.

    "VLAN_INTERFACE": {

        "Vlan1120": {},

        "Vlan1120|5.5.5.5/29": {

            "gwaddr": "5.5.5.1"

        }

The STATIC_ROUTE stuff from documentation does not seem to do anything either..

ala 

"STATIC_ROUTE": {

         "11.11.11.0/24": {

        "distance": "10",

        "nexthop": "192.168.10.1"

    },

For this one I did set       "frr_mgmt_framework_config": "true",

 in DEVICE_METADATA first.
