Juniper EX series as an alternative to Cisco Catalyst?
Cisco vs Juniper
Does anyone has any real life experience with designing and especially working (=managing) with the Juniper EX switching series networks as an alternative to the typical Cisco core/distrubution/access layer model?
We're currently designing a completely new network at an existing +/- 2000 users university campus network in Peru and both Cisco and Juniper are still in the running. We know Cisco and we know what to expect and we know it's expensive. Juniper is able to deliver more (all Gigibit Ethernet ports) for the same price (or less) but is the technology reliable and ready for the future? What are the caveats? They say they step away from Spanning tree and go for a all L3 network. But do we really want that? Are the disadvantages of Spanning tree so big that you want to completely step away from it?
The network is very high demanding. No fancy and/or no high I/O intensive applications.
I'm not looking for an answer from Cisco veterans or die hard Cisco fans that want to give me a religious answer. I'm looking for someone that really knows both technologies in typical medium sized setups and want to tell something about the pros and cons to have a better answer for the sales people.
Also a link to a good and recent (up to date) article that talks about this would be helpful. I found a few but they were old or not relevant.
