Garbage-Collection
##################

Test to verify RIP **garbage collection timer** for removing stale routes.
This validates the **two-stage removal process:** After routes are marked **invalid** by the
``timeout timer`` (``metric 16``), the ``garbage collection timer`` **completely removes** them
from the routing table. This test simulates neighbor loss by removing RIP configuration.

*********************************
Test RIP Garbage Collection Timer
*********************************

Description
===========

Verify ``RIP`` **garbage collection timer** completely removes invalid routes.
**DUT0** advertises the route ``10.10.10.0/24`` to **DUT1**. Then ``RIP`` is deleted from
**DUT0** to simulate a neighbor loss. After 5 seconds, the route is marked
as **invalid** with ``metric 16``. After an additional 5 seconds, the route
is **completely removed** from the routing table. This demonstrates the **two-stage process**
that prevents stale routes from persisting indefinitely.
