###########################
Rip Interface Route-Map Vrf
###########################

Scenario to verify RIP **interface route-map** configuration within a VRF.

The ``set protocols vrf <vrf> rip interface <ifc> route-map in <name>`` command applies
a route-map to filter incoming RIP route updates on a specific interface inside a VRF.
The ``set protocols vrf <vrf> rip interface <ifc> route-map out <name>`` command applies
a route-map to filter outgoing RIP route updates on a specific interface inside a VRF.

Each interface accepts at most one route-map in and one route-map out. Configuring a
second route-map in the same direction will overwrite the previous one.

Additionally, route-map rules that set metric values outside the valid RIP range (1-16)
are rejected at commit time when applied to a RIP interface inside a VRF.

***********************************
Test RIP VRF Interface Route-Map In
***********************************

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

Test RIP **interface route-map in** filtering within a VRF (``RIP-VRF``).
**DUT1** redistributes two connected dummy routes (``10.10.10.0/24`` and
``10.20.20.0/24``) into RIP inside ``RIP-VRF``. **DUT0** applies a route-map
on its incoming VRF interface that only permits ``10.10.10.0/24``.
**DUT0** learns only the permitted route; ``10.20.20.0/24`` is filtered out.

************************************
Test RIP VRF Interface Route-Map Out
************************************

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

Test RIP **interface route-map out** filtering within a VRF (``RIP-VRF``).
**DUT0** redistributes two connected dummy routes (``10.10.10.0/24`` and
``10.20.20.0/24``) into RIP inside ``RIP-VRF`` and applies a route-map on
its outgoing VRF interface that only permits ``10.10.10.0/24``.
**DUT1** learns only the permitted route; ``10.20.20.0/24`` is not advertised.

**********************************************
Test RIP VRF Interface Route-Map In Set Metric
**********************************************

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

Test RIP **interface route-map in** with ``set metric 5`` within a VRF (``RIP-VRF``).
**DUT1** redistributes a connected dummy route (``10.10.10.0/24``) into RIP
inside ``RIP-VRF``. **DUT0** applies a route-map on its incoming VRF interface
that sets the metric to 5. **DUT0** learns the route with metric **6** (5 + 1 hop).

***********************************************
Test RIP VRF Interface Route-Map Out Set Metric
***********************************************

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

Test RIP **interface route-map out** with ``set metric 5`` within a VRF (``RIP-VRF``).
**DUT0** redistributes a connected dummy route (``10.10.10.0/24``) into RIP
inside ``RIP-VRF`` and applies a route-map on its outgoing VRF interface that
sets the metric to 5. **DUT1** learns the route with metric **6** (5 + 1 hop).

******************************************
Test RIP VRF Interface Route-Map Overwrite
******************************************

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

Test that each RIP VRF interface accepts at most **one route-map per direction**.
Configuring a second route-map in the same direction overwrites the previous one.
**DUT1** redistributes two connected dummy routes (``10.10.10.0/24`` and
``10.20.20.0/24``) into RIP inside ``RIP-VRF``. **DUT0** configures two
route-maps in the **in** direction: ``VRF-FILTER-A`` (permits only
``10.10.10.0/24``) and ``VRF-FILTER-B`` (permits only ``10.20.20.0/24``).
Only the last configured route-map (``VRF-FILTER-B``) takes effect.
**DUT0** learns ``10.20.20.0/24`` and does not learn ``10.10.10.0/24``.

********************************************************
Test RIP VRF Interface Route-Map Invalid Metric Rejected
********************************************************

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

Test that a route-map with a **metric value outside the valid RIP range (1-16)**
is rejected at commit time when applied to a RIP interface inside a VRF.
**DUT0** configures a route-map ``INVALID-METRIC`` with ``set metric 20`` and
applies it to a RIP interface in ``RIP-VRF``. The commit must fail with a
validation error indicating that metric 20 is outside the RIP range.
