Juniper RSVP-TE implementation is mostly compatible with Cisco IOS , 
exlcuding
topic such as DS-TE , Fast-reroute ( one-to-one protection ). Notice however 
that
things may change when considering IOS-XR.

You can classify packets based on 802.1p and forward them to different LSP 
with class based forwarding
( doesn't have to be DS-TE , works also with normal TE) - works great on 
E-FPC. But it is not different l2circuit - y
ou can choose LSP but not l2circuit since logical interface can be assigned 
to only one l2circuit
