The 3560 doesn't support regular bridging, only "fallback bridging" that
generally just works for non-IP.

You could use a "real" router to do it, like a 2800.

Alternatively, if you can accept that the spanning trees collapse, you
can melt together the VLANs with to access ports loop to each other and
members of each VLAN. You have to be a little careful though.
