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)

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
