802.1d Bridging Options
Spanning tree protocol is used to prevent bridge loops. Unlike router loops, bridge loops could
theoretically never time out because unlike routers, bridges do not decrement the TTL counter. If you
have anything more than a simple ethernet bridge, you should leave STP enabled. The defaults suffice
for most. The benefits of using STP far outweigh the detrimental effects of turning it off when it's
needed.
