If you are using EX Series, take a look at PVLANs - http://www.juniper.net/techpubs/en_US/junos10.0/topics/concept/private-vlans-ex-series.html

This allows you to split broadcast domains into separate isolated broadcast subdomains to constrain connectivity while at the same time keeping devices in the same subnet and thereby reducing your overall IP address utilization.
