##########
Capability
##########

Scenario to verify BGP **peer-group capability** inheritance.
When ``capability dynamic`` is configured on a peer-group, members advertise
the dynamic capability during session setup, allowing future capability changes
without resetting the session.

*******************************************************
Test iBGP - Peer-group capability dynamic is negotiated
*******************************************************

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

Test that ``capability dynamic`` configured on a peer-group is inherited by its
members. Both peers advertise the dynamic capability and it is successfully
negotiated.

*******************************************
Test iBGP - Without ORF receives all routes
*******************************************

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

Baseline test without ORF. DUT1 advertises two networks (1.1.1.0/24 and
2.2.2.0/24) and DUT0 receives both. This serves as a comparison point for
the ORF test.

**************************************************************************
Test iBGP - Peer-group capability ORF prefix-list filters routes at source
**************************************************************************

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

Test BGP ``capability orf prefix-list`` configured on a peer-group. DUT0 is configured
with ORF send mode via peer-group and has a prefix-list that only permits 1.1.1.0/24.
DUT1 receives the filter and only sends 1.1.1.0/24, filtering 2.2.2.0/24 at source.
