Setting Secondary Delay: to a higher number would keep the switchover to Failover longer.

Unless you are looking for a CLI command like
--
service failover force
--
but somehow this would need to be reset back to primary.  And the secondary link could also fail while the primary is OK again.

Other than setting Secondary Delay: to 30 minutes or so for notably bad primary links, I'm not not sure of a true answer.

I suppose we could keep track of the time between switches and increase the effective Secondary Delay if there are a lot of failover switches, but that can get complicated.

Currently your best option is to manually define routes using "ip route add ..."

Great to hear, I use it all the time but the good news is my primary link is very robust (knock on wood) and the failover is seldom triggered.
