Try searching "dladm simnet". You should get a bunch of hits, including
this fairly practical one:
He was simulating routers, but the process is the same. (And, in fact,
"simnet" links were added during our bridging/TRILL project in order to
test bridging and TRILL.)
On that site, you'll also find links to a separate driver you can
download and install called "hxbt:"
It looks like a variant of the "hitbox" driver we used to use at Sun for
testing WAN-related behavior.

No problem. You just need a bunch of links to bridge together, and then
you can set up arbitrary instances of regular bridges (with or without
STP) and TRILL bridges.
Simnet links are just point-to-point, so they're perhaps not too
interesting if you're deeply concerned about details such as Appointed
Forwarder operation or DR election, at least on those links, but you can
use one or two real external Ethernet interfaces to probe those
behaviors as well.
