Shouldn't the source-bridge command look like this...
"source-bridge transparent 2 10 100"
I'm doing this off the top of my head, but I seem to remember that the
target ring number should be the 3rd number in the command. In your config,
you have the target ring number first. Am I right?
One more thing... Your interface command, "bridge-group X" should point to
the middle number, which is the bridge number. The way you have it
configured, you should have typed in "bridge-group 10".
Again, I'm doing this off the top of my head, so don't berate me! :-)
