|
| Filename | Overview |
|---|---|
| zebra/zebra_vty.c | Core implementation of brief JSON mode; adds brief flag through the call chain and manages JSON accumulation correctly. Minor inconsistencies: ID-based brief query uses vty_json (pretty) while bulk brief uses vty_json_no_pretty, and brief mode disables streaming flush causing full in-memory accumulation. |
| lib/nexthop.c | Adds brief parameter to nexthop_json_helper; correctly gates verbose fields. Side effect: vrf field is now emitted before type-specific detail fields in non-brief mode, changing serialisation order for existing JSON output. |
| zebra/zebra_rnh.c | Signature update for show_nexthop_json_helper; all existing callers correctly pass false for brief. |
| doc/user/zebra.rst | CLI reference updated with [json [brief]] syntax and a brief prose description of what each modifier omits; accurate and complete. |
| tests/topotests/all_protocol_startup/test_all_protocol_startup.py | New test_show_nexthop_group_rib_brief_json covers all five command variants. Commands 1 and 2 validate per-entry field constraints; commands 3–5 only check top-level structure, leaving brief-mode regressions on singleton/type-filtered paths undetected. |

**Per-entry field validation missing for commands 3–5**
Commands 3 (`singleton ip`), 4 (`singleton ipv6`), and 5 (`zebra`) only validate that the top-level output is a dict. They do not iterate entries and verify that `type`, `refCount`, and `timeToDeletion` are absent — the same check that command 1 performs via `_check_brief_nhg_entry`. If a regression reintroduced those fields for any of those filter paths the tests would pass silently.

**Non-brief nexthop JSON field ordering change**
The `vrf` field is now emitted earlier — before `resolver`, `active`, `onLink`, `linkDown`, and the type-specific extensions — rather than after them as before. JSON semantics are unaffected, but any downstream tooling that relies on `jq` slurp order or exact serialisation snapshots in non-brief mode will see a change. Mention this in the commit message so it's searchable.

Commands 3 (singleton ip), 4 (singleton ipv6), and 5 (zebra) only validate that the top-level output is a dict. They do not iterate entries and verify that type, refCount, and timeToDeletion are absent — the same check that command 1 performs via _check_brief_nhg_entry. If a regression reintroduced those fields for any of those filter paths the tests would pass silently.
