In this XML configuration snippet, BGP instances are configured on network-instance on OpenConfig and on container BGP on OcNos side. Due this difference the delete process need to handle if the operation is trying to delete one VRF instance or the entire BGP instance.

When using OpenConfig, the BGP object on OcNOS database is only deleted by the delete on "default" network-instance. When the delete is execute on VRF network-instance it only deletes the given VRF instance.

If there are VRF instances configured and a delete operation is executed on "default" network-instance, it going to clean only entries configured on "default" network-instance. To remove VRF instances, the user needs to apply a operation delete on VRF instances.

This configuration was introduced in OcNOS version 5.1.

Here is a sample NetConf Payload to delete BGP instance.

Delete VRF instance:

Delete default instance:

Here is a sample OcNOS NetConf Payload to delete BGP instance.

Delete VRF instance:

Delete default instance:

On OpenConfig BGP datamodel the container global do not have any key to identify a single BGP instance, but the BGP AS information is placed under xpath /oc-netinst:network-instances/network-instance/protocols/protocol/bgp/global/config/as.

On IPI BGP datamodel, the BGP AS information is a key for BGP container, and it does not allow the delete on xpath /ipi-bgp:/bgp/bgp-instances/bgp-instance/config/bgp-as to avoid delete its own instance key.

In this case, when translation framework detects a delete or remove operation on following OpenConfig xpaths:

It will trigger an error message to NETCONF client and do not execute the delete operation.

To avoid this issue, when user needs to delete or remove a configuration under OpenConfig xpath /oc-netinst:network-instances/network-instance/protocols/protocol/bgp/global/config, user must adds a "delete" or "remove" operation directly on the leaf or leaves desired to be removed, rather than delete the entire container.
