Ming,
I don't see the reason for the 'bridge irb'. If the cat has all 20
VLANs on it, the 7200 trunk carries all 20, and each FE trunk on the 3640
carries 5 of the 20, wouldn't that do it? Of course you'll make sure that
the unnecessary VLANs are kept off the individual FE trunks. Or did I miss
something?

In this case, the best take is to configure "bridge irb". You configure
20 bridge groups and 20 bvi interfaces. you also configure 5
subinterfaces under each FE and 20 subinterfaces under GE.
And rest of it, you should be figure it out pretty easily.
