Hello there,
I've got two offices and these are connected via GRE IPSec + OSPF. Both have failover channels + script which controls switching to failover and back to main.
Everything works fine until Failover comes in. Connections interruptions are quite common.
So I want some kind of redundant GRE-tunnel, but which will be up only if failover switch will be performed. Is there some kind of easy way to achieve this?
