Dear Wilder Rodrigues,

In my environment , it is different.

1) Create new VPC (Redundant VPC offering)

2) Create new tier

3) Create new VM Instance on this tier

4) Check Redundant state (good)

r-41-VM Redundant state:BACKUP

In the above, 
both r-40-VM and r-41-VM is , continues to send the VRRPv2 Advertisement.

In my environment, Isolated network's redundant router is no problem.

Dear Wilder Rodrigues,

In my environment , it is different.

1) Create new VPC (Redundant VPC offering)

2) Create new tier

3) Create new VM Instance on this tier

4) Check Redundant state (good)
r-40-VM Redundant state:MASTER
r-41-VM Redundant state:BACKUP
