Remove-Private-As
#################

Test BGP **address-family ipv6-unicast remove-private-as** functionality. When a router receives
routes from a neighbor using a private AS number (64512-65534), those private AS numbers appear
in the AS-path. The remove-private-as command strips these private AS numbers from the AS-path
before advertising routes to an eBGP peer.

*******************************************************************
Test eBGP IPv6 - Without remove-private-as shows private AS in path
*******************************************************************

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

Baseline test showing default behavior where private AS numbers are visible in the
AS-path. DUT1 uses private AS 65001 and originates route 2001:db8:100::/64.
DUT0 (AS 100) receives the route and forwards it to DUT2 (AS 200).

advertising to eBGP peers. DUT1 uses private AS 65001 and originates route
2001:db8:100::/64. DUT0 (AS 100) has remove-private-as configured toward DUT2.
