The MD-CLI engine for mixed and model-driven configuration modes only allows names for filters, router instances, and services; IDs are not supported.
Table: Key differences between classic CLI and MD-CLI lists key differences between classic CLI and MD-CLI.
| Classic CLI engine for mixed mode | MD-CLI engine for mixed and model-driven mode |
|---|---|

/li/li-source (name only) |
li>li-source>nat>classic-lsn-sub>router li>li-source>nat>dslite-lsn-sub>router li>li-source>nat>nat64-lsn-sub>router (router ID or name) |
/li/li-source/nat/nat44 /li/li-source/nat/dslite /li/li-source/nat/nat64 (router name only) |
li>mirror-dest-template>layer-3-encap>router (router ID or name) |

Compared to classic configuration mode, mixed and model-driven configuration modes primarily use loose references, where the object referenced does not have to exist in the system before it is referenced. For example, subscriber-1 is referenced in li-source but does not need to be created on the system beforehand.
In classic configuration mode, when an LI filter (li-ip-filter, li-ipv6-filter, and li-mac-filter) is configured:
LI filter entries can be referenced even if the LI filter is not associated (under the config>li>li-filter-associations context) with a filter in the config>filter context.
After an LI filter entry is referenced in the li-source, the LI filter association that contains the specified LI filter cannot be deleted. Therefore, the LI filter association can only be deleted if the LI filter entries are no longer referenced in the li-source.
When an LI filter entry is not referenced in li-source:
If li-filter-associations associates an LI filter name with a filter ID, the deletion of either the filter ID or the LI filter name, also deletes the li-filter-associations.
After li-filter-associations associates an LI filter name with filter name, the deletion of either the LI filter name or the filter name is always denied and no roll back to a configuration mode is completed without the LI filter name or the filter name.
In mixed configuration mode:
An LI filter entry can be referenced in li-source, when the LI filter is first associated with a filter in the config>filter context under the config>li>li-filter-associations context.
LI filter association between an LI filter name and a filter ID is not allowed.
After an LI filter entry is referenced in the li-source, the LI filter association that contains the specified LI filter cannot be deleted. Therefore, the LI filter association can only be deleted if the LI filter entries are no longer referenced in the li-source.
When an LI filter entry is not referenced in li-source; after li-filter-associations associates an LI filter name with filter name, the deletion of either the LI filter name or the filter name is always denied and no roll back to a configuration mode is completed without the LI filter name or the filter name.
