Thanks What Lies Beneath for your quick response.
Well, yes I must have misunderstood F5's output. The fact is that for instances 1 and 2, the regional root bridge MAC address listed by F5 is itself, so I was confused:root@F5(Standby)(tmos) show net vlan
Net::Vlan: 603

As per the active F5... well at the moment they are both standby because I configured VLAN failsafe on both vlans.
This is the second F5's output:root@F5-2(Standby)(tmos) show net vlan
Net::Vlan: 600

The configuration is the same.
