I am moving from Cisco to Aruba, and I am wondering how much configuration is needed for spanning tree RPVST to work properly.
In general it seems like I don't really need to do much at all and the defaults may be good enough. But I just want to check and make sure.
I am not seeing any problems with this very minimalist configuration, but it is vaguely disconcerting to see that both the primary 10 gigabit fiber and the 2 gigabit backup path are both listed as forwarding in the spanning tree status.
Is it permitted to have redundant paths both forwarding between switches without creating broadcast storm loops?
