vrrp remains in FAULT state when dualstack is configured. #2688
Description
Describe the bug
VRRP status remains as FAULT.
To Reproduce
1. Create vlan interface 200
2. Assign interface ip 200.1.1.1
3. Assign interface ipv6 address 200::1
4. Enable ipv6 on interface v200
5. Configure vrrp interface 2
6. Configure vrrp ip address 200.1.1.100
7. Configure vrrp ipv6 address 200::100
8. Add vlan 200 to a port which is up

Let me know if this issue is fixed in any later release as the issue seems related to ipv6 . If i remove the vrrp ipv6 configuration vrrp instance comes up as Master. Also if the vlan is already added to port (interface up) , then dualstack config works .
Logs given below when dualstack is confgured
