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

This scenario demonstrates how to configure prefix-list filtering for BGP neighbors.
A prefix-list defines which IP prefixes can be advertised to or received from a BGP neighbor
based on IP prefix matching. Unlike route-maps which can match many attributes (AS-path, communities, etc.),
prefix-lists are optimized for simple and efficient IP prefix filtering.
In this test, DUT0 is configured with a prefix-list that only permits advertisement of 1.1.1.0/24,
preventing the directly connected network 10.215.200.0/24 from being advertised to DUT1.
This is useful for controlling which routes are shared with BGP peers.

*************************
Test BGP with prefix-list
*************************

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

Test to verify that prefix-list filtering controls which routes are advertised to BGP neighbors.
DUT0 exports only routes matching prefix-list pl1 (1.1.1.0/24).
DUT1 should receive route 1.1.1.0/24 but NOT the connected network 10.215.200.0/24.
