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 [create] xpath [/frr-routing:routing/control-plane-protocols/control-plane-protocol[type='frr-bgp:bgp'][name='bgp'][vrf='default']/frr-bgp:bgp/global/afi-safis/afi-safi[afi-safi-name='frr-routing:ipv4-unicast']] value [(none)] 2021/06/02 08:11:24 BGP: [SWK28-M149C] northbound callback: event [prepare] op [create] 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']] value [(none)] 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-type] value [as-specified] 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"? Regards, Yeping Xing xingyeping@163.com
