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

Scenario to verify BGP **peer-group address-family ipv6-unicast capability orf** inheritance.
The orf prefix-list option enables Outbound Route Filtering, which allows a router to send
its inbound prefix-list filters to a neighbor so the neighbor can apply them as outbound
filters. This reduces bandwidth and processing overhead by filtering unwanted routes at the
source. When configured on a peer-group under address-family ipv6-unicast, members inherit
the ORF capability for IPv6 routes.

************************************************
Test iBGP IPv6 - Without ORF receives all routes
************************************************

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

Baseline test without ORF. DUT1 advertises two networks (2001:db8:10::/64 and
2001:db8:20::/64) and DUT0 receives both. This serves as a comparison point for
the ORF test.

Test iBGP IPv6 - Peer-group capability ORF prefix-list filters routes at source
*******************************************************************************

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

Test BGP ``capability orf prefix-list`` configured on a peer-group under address-family
ipv6-unicast. DUT0 is configured with ORF send mode via peer-group and has a prefix-list
that only permits 2001:db8:10::/64. DUT1 receives the filter and only sends 2001:db8:10::/64,
filtering 2001:db8:20::/64 at source.
