You can try the same trick as with ex-series (yes, it's quite possible
to run full-view on ex-4200 series switch and some people do that in
production networks). I never tried it at SRX (do not have one yet),
so if you'll try it - I'd like to hear your experience.
Very advanced sort of design :) EX3200/4200 can only support 32k active
prefixes in FIB. Sure you can keep as many prefixes in RIB as Control
Plane capable to hold and only few prefixes in FIB but, I am sorry, what
for? What is the adventure of keeping that hell of routes in RIB if you
rely on something other for real switching? To feel cool issuing "show
route summary" which shows 600k routes instead of 6? :)
The problem with EX in ISP applications is very limited MPLS
capabilities. So if you want VPLS or L3VPN in some remote location, EX
will not save you although it has way higher forwarding performance.
