Route-Reflector-Allow-Outbound-Policy
#####################################

Scenario to verify BGP **route-reflector allow-outbound-policy** parameter.

By default, a Route Reflector does not apply outbound route-maps to routes it reflects
to its iBGP clients. This is because reflected routes should maintain their original
attributes to ensure consistent routing decisions across the network. The
``route-reflector allow-outbound-policy`` parameter changes this behavior, allowing the
RR to apply export route-maps to reflected routes.

This is useful in scenarios where the RR needs to modify attributes like MED, community,
or AS-path prepend for routes being reflected to specific clients. In this test, **DUT0**
acts as a Route Reflector for **DUT1** and **DUT2**. DUT1 announces a route, and DUT0
has an export route-map configured toward DUT2 that sets MED to 500. Without the
``allow-outbound-policy`` parameter, the route-map is ignored. With it enabled, the MED
modification takes effect on the reflected route.

**********************************************
Test BGP Route Reflector Allow Outbound Policy
**********************************************

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

This test demonstrates the effect of ``route-reflector allow-outbound-policy`` on
Route Reflector behavior. **DUT0** (RR) has an export route-map configured toward
**DUT2** that sets MED to 500. Without ``allow-outbound-policy``, the route-map is
ignored and the reflected route from **DUT1** reaches DUT2 with its original MED (0).
After enabling ``allow-outbound-policy``, the route-map is applied and DUT2 receives
the route with MED 500.
