[Advanced] Dynamic routing(RIP) function not supported

[JohnnyWuLinksys]

Description
In the previous jnap base image with nat and rip routing mode can select
However in usp base image no these option(default still nat)

Steps

1. Menu > Advanced Settings
2. Check dynamic routing item

Current result
No Advanced routing, which support dynamic routing selection in previous version

Expected result
Previous supported function should still works

Information
Pinnacle 2.0 FW: 1.2.2.26062820
Linksys Now Version: 2.5.0.700525

Severity
S2

Additional context

🔍 Automated investigation (preliminary triage)

Line: 2.x / USP (TR-369)

Root cause:

• Trigger (firmware/data-model): On the USP base image, the router does not expose the dynamic-routing (RIP) capability. The USP data-model definition explicitly documents that RIP is unsupported and that NAT is per-interface rather than a global toggle.
• UI consequence: Because the underlying USP model has no RIP/global-NAT capability to bind to, the 2.x Static Routing page renders no NAT vs. Dynamic Routing selector — hence the missing "Advanced routing" option the JNAP (1.x) image had.

Evidence:

1. USP data-model definition (usp_framework) explicitly states RIP is not supported and NAT is per-interface — the capability simply isn't in the USP model the 2.x UI binds to (usp-definitions/network/static_routing.yaml L1-L10):

# Static routing IPv4 forwarding rules
# SSH-verified 2026-03-09 via Device.Routing.Router.1.IPv4Forwarding
# ...
# RIP (Device.Routing.RIP.Enable) is NOT supported on this firmware.
# NAT is per-interface (Device.NAT.InterfaceSetting.{i}.Enable), not
# a global toggle like JNAP's isNATEnabled.

2. The JNAP (1.x) UI drives the NAT / Dynamic Routing (RIP) segmented control from a global flag (PrivacyGUI 1.x static_routing_view.dart L115-L126):

selected: state.setting.isNATEnabled
    ? RoutingSettingNetwork.nat
    : RoutingSettingNetwork.dynamicRouting,
// ...
title: loc(context).nat, value: RoutingSettingNetwork.nat,
title: loc(context).dynamicRouting, value: RoutingSettingNetwork.dynamicRouting,

The 1.x feature-state carries isNATEnabled / isDynamicRoutingEnabled (a global routing mode). The USP model has no equivalent global toggle.

3. The 2.x USP Static Routing view (usp_static_routing_view.dart) and its static_routing_feature_state.dart contain no NAT / dynamic-routing / RIP selector at all — grep for nat|dynamicRouting|SegmentedButton|routingMode returns nothing in the 2.x page:

$ grep -niE 'nat|dynamicRouting|SegmentedButton|routingSetting' \
    lib/page/static_routing/views/usp_static_routing_view.dart
(no matches)

Confidence: Medium — root cause is code-confirmed but spans layers: whether RIP/dynamic-routing parity with the JNAP image is achievable depends on the USP firmware exposing the capability (currently documented as unsupported), which needs firmware-team confirmation.
