I have no experience with the Juniper ISG firewalls, and 
very limited experience (which I hope to forget) with the 
Extreme kit as well.

However, if you're talking about standard 802.1AX (used to 
be 802.3ad) link aggregation, your best chance is to use 
LACP between both devices to ensure the link aggregation 
works perfectly.

I'd research LACP support on both platforms, first. 

Hope this helps.

Cheers,

Mark.
