CRB is used when you want to route and bridge the same protocol,
but not on the same interfaces. With this config devices in the bridged
domain cannot talk to devices in the routed domain. IRB is used when
you want to route and bridge the same protocol on the same interface.
With this config devices in the bridged domain can talk to devices in
the routed domain through the usage of the Bridge Virtual Interface
(BVI).
CRB is a subset of IRB. You could get CRB functionality by
saying "bridge crb" or saying "bridge irb" without adding the additional
"bridge 1 route ip" or similar command.

OK peeps, I'm embarrassed to admit it, but even after reading through
the
doc CD and working through several practice labs I'm having a hard time
determining when to us CRB vs IRB. Can someone put it in plain English
using
words 3 syllables or less please? ;)
