How does constant unknown unicast flooding affect networks? Better yet, how to design in mitigation ? is it all about lower arp timeouts below 300 secs so to artificially prop-up bridge tables and keep them fresh? My goodness that's making arp very busy.
Make sure your arp timeouts are aligned with your bridge timeouts (keep arp timers lower than bridge timeouts). Easiest way to do it is (as you say) lower arp timers. Another way is of course to raise bridge timeouts.
