[FROG] Using Northbound gPRC to configure BGP

[xingyeping at 163.com]

Hi All.

I'm trying to configure BGP with Northbound gPRC. I'm using a Golang client to send Json format configuration to BGPD and now I can send
some configuration to BGPD，the question is I can't configure the "afi-safis"。The configuration is underneath：

{
 "frr-routing:routing": {
  "control-plane-protocols": {
   "control-plane-protocol": [{
    "type": "frr-bgp:bgp",
    "name": "bgp",
    "vrf": "default",
    "frr-bgp:bgp": {
     "global": {
      "local-as": 100,
      "router-id": "2.2.2.2",
      "afi-safis": {
       "afi-safi": [{
        "afi-safi-name": "frr-routing:ipv4-unicast",
        "frr-routing:ipv4-unicast": {
         "network-config": [{
          "prefix": "192.168.155.0/24"
         }, {
          "prefix": "192.168.166.0/16"
         }]
        }
       }]
      }
     },
     "neighbors": {
      "neighbor": [{
       "remote-address": "4.4.4.4",
       "neighbor-remote-as": {
        "remote-as-type": "as-specified",
        "remote-as": 100
       }
      }]
     }
    }
   }]
  }
 }
}
    The red part can't deliver to BGPD，and the log is：
2021/06/02 08:11:24 BGP: [SWK28-M149C] northbound callback: event [prepare] op [modify] xpath [/frr-routing:routing/control-plane-protocols/control-plane-protocol[type='frr-bgp:bgp'][name='bgp'][vrf='default']/frr-bgp:bgp/global/router-id] value [2.2.2.2]

2021/06/02 08:11:24 BGP: [SWK28-M149C] northbound callback: event [prepare] op [modify] xpath [/frr-routing:routing/control-plane-protocols/control-plane-protocol[type='frr-bgp:bgp'][name='bgp'][vrf='default']/frr-bgp:bgp/neighbors/neighbor[remote-address='4.4.4.4']/neighbor-remote-as/remote-as] value [100]

    I'm also tried to replace the "network-config" to "frr-bgp:network-config",but it's also does't work.

    Can anyone tell me the correct json format of "afi-safis"?
