Distribute-List Prefix-List
###########################

Test to verify RIPng **distribute-list prefix-list** configuration for route filtering.
The ``set protocols ripng distribute-list prefix-list in <list>`` command filters incoming RIPng
routes globally across all interfaces using a prefix-list. The ``set protocols ripng distribute-list
prefix-list out <list>`` command filters outgoing RIPng routes globally. These commands provide
centralized control over route acceptance and advertisement across all RIPng neighbors.

*****************************************
Test RIPng Distribute-List Prefix-List IN
*****************************************

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

Test RIPng **distribute-list prefix-list in** filters incoming routes globally across all interfaces.
DUT1 redistributes two dummy networks into RIPng, the 2001:db8:100::/64 and 2001:db8:200::/64 networks.
DUT0 is configured with a global incoming distribute-list that permits only 2001:db8:100::/64 and
denies all other routes. The test verifies that DUT0 accepts the 2001:db8:100::/64 route but rejects
the 2001:db8:200::/64 route, demonstrating that the global prefix-list filter is working correctly
for all incoming RIPng updates.

Test RIPng Distribute-List Prefix-List OUT
******************************************

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

Test RIPng **distribute-list prefix-list out** filters outgoing routes globally across all interfaces.
DUT0 redistributes two dummy networks into RIPng, the 2001:db8:100::/64 and 2001:db8:200::/64 networks.
DUT0 is configured with a global outgoing distribute-list that permits only 2001:db8:100::/64 and
denies all other routes. The test verifies that DUT1 receives the 2001:db8:100::/64 route but does
not receive the 2001:db8:200::/64 route, demonstrating that the global prefix-list filter is working
correctly for all outgoing RIPng advertisements.
