Ping working successfully, tested with both IPV4 and IPV6.

steps :

--------------

1 network - Dual stack, 2 subnets (1-V4, 1-V6)
2 ports P1 P2.
2 VM's P1 -> VM1, P2 -> VM2
Update P1 with AAP.
Add router
Add ipv6 subnet to router.
Add route in router for AAP.
Add gateway in VM2 for ipv6

ping VM2 to P1 AAP - working
ping VM1 to VM2 - working
ping VM1 P1 AAP to VM2 - working

--------------
