</state>
</interface>
</interfaces>
</bfd>
</data>
</rpc-reply>
Restrictions
The command /bfd/interfaces/interface[id='eth1']/config uses ipi-oc-bfd-deviations to set a constraint on OpenConfig where all three intervals attributes must be set together. So leaves desired-minimum-tx-interval, required-minimum-receive and detection-multiplier must be present in payload so that it can be accepted. For deletion, operation “delete” or “remove” must be present in the three attributes at the same time.
/bfd/interfaces/interface[id='eth1']/interface-ref/config/interface must be the same as /bfd/interfaces/interface/id.
