Spanning tree/ connecting single LTM to 2 different redundant networks

Do the following

 

Configure the network devices with more prirority for the vlans defined on the LTM's

 

On the interfaces connected to the F5 LTM's -

 

1)enable rootguard - so the LTM's cant be the root

 

2)Disable bpduguard on the interfaces (If you enable on the devices globally

 

IN LTM

 

From the spanning tree options select the RSTP.

 

In the interface -

 

you need to enable the spanning tree .

 

STP link type - p2p

 

Uncheck(disable) the STP egdeport ans STP edgeport detection

 

once you are done - you will see a forwarding and blocking(alternate) in the LTM
