#############################
Redistribute Connected Metric
#############################

Test to verify RIPng **metric** configuration for redistributed connected IPv6 routes.
The ``redistribute connected metric`` command sets the metric value for connected routes
redistributed into RIPng. Valid values are 1-16, where ``metric 1`` is the default when not
specified. This test validates the default behavior (metric 1), custom valid metric values,
and the special case of ``metric 16`` where routes are not announced (infinity).
RIPng is the IPv6 version of RIP.

********************************************
Test RIPng Default Metric With Default Value
********************************************

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

Test RIPng **redistribute connected metric** with the **default value** (``metric 1``).
When metric is not explicitly configured, RIPng uses ``metric 1`` by default.
**DUT0** redistributes the connected IPv6 route ``2001:db8:100::/64`` with the default metric.
**DUT1** learns this route with ``metric 2`` (incremented by 1 hop). The route is
installed in the routing table and connectivity is verified with ping.

******************************************
Test RIPng Default Metric With Valid Value
******************************************

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

Test RIPng **redistribute connected metric** with a valid value (``metric 5``).
**DUT0** redistributes the connected IPv6 route ``2001:db8:100::/64`` with ``metric 5``.
**DUT1** learns this route with ``metric 6`` (incremented by 1 hop). The route is
installed in the routing table and connectivity is verified with ping.

****************************************
Test RIPng Metric 16 Route Not Announced
****************************************

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

Test RIPng **redistribute connected metric 16** - route is **not announced**.
When **DUT0** redistributes ``2001:db8:100::/64`` with ``metric 16`` (infinity), the route
is **not announced** to neighbors because it is already unreachable at the source.
**DUT1** does not see the route in RIPng database, does not install it in routing table,
and **ping fails**.
