Spanning Tree Protocol

I am working with 2 BIG IP LTM in HA (Active/Standby with a Network failover between then). The actived one has configured RSTP mode and the other one just "pass through".     Any suggest...

You definitely do not want to have one with STP enabled and one without - suppose that STP is required to break loops in your network. When you failover (say, due to a disk failing in the active), your network will go down because the new box fails to break the loop.

 

 

If you don't need STP, then you should disable it on the active box as well.
