Question

You are generating a JSON payload from the ietf-interfaces YANG model to configure a GigabitEthernet2 interface. The requirement is that the interface obtain its IPv4 address via DHCP rather than a static address, while keeping the interface administratively enabled. Given the model defines the ipv4 container with a mutually-exclusive choice between 'address' (list of static addresses) and 'dhcp' (an empty leaf/presence), which JSON body correctly represents this configuration?

Accepted Answer

{ "ietf-interfaces:interface": { "name": "GigabitEthernet2", "enabled": true, "ietf-ip:ipv4": { "dhcp": [null] } } }

Answer

{ "ietf-interfaces:interface": { "name": "GigabitEthernet2", "enabled": true, "ietf-ip:ipv4": { "address": [ { "ip": "dhcp" } ] } } }

Answer

{ "ietf-interfaces:interface": { "name": "GigabitEthernet2", "enabled": true, "ietf-ip:ipv4": { "dhcp": true, "address": [ { "ip": "0.0.0.0", "netmask": "0.0.0.0" } ] } } }

Answer

{ "ietf-interfaces:interface": { "name": "GigabitEthernet2", "enabled": true, "dhcp": "enabled" } }
