Primary gateway with static ip address not activating

Hi @jaclaz
I have read the post at http://forum.mikrotik.com/t/failover-routeros-v7/183285/1 several times but am not sure what applies to my situation. I have tried looking for documentation on targets and scopes and have found some answers but am still confused.

I understand up till the point where my default route via my primary gateway has to have a lesser distance value than that of the route from the secondary gateway.

I am however confused by scopes and targets. Still, here are the commands I plan to run.

add dst-address=8.8.8.8/32 gateway=122.176.152.1 scope=10 comment="Primary check IP via ether1"
add dst-address=208.67.222.222/32 gateway=192.168.100.1 scope=10 comment="Secondary check IP via ether2"
add dst-address=0.0.0.0/0 gateway=8.8.8.8 distance=1 target-scope=10 check-gateway=ping comment="Primary default route"
add dst-address=0.0.0.0/0 gateway=208.67.222.222 distance=2 target-scope=10 check-gateway=ping comment="Secondary default route"

Are these accurate for my situation?
