We’re looking at streamlining some of our network operations where we have to upgrade our edge switches from some 8-14 year old Bay Stack/Nortel switches that are starting to fail. The overall design is that we’re looking at all L3 traffic to be handled by our Core switch (Juniper EX-4200 VC) and have our employee network segregated from our Student network in hopes to protect our production database servers. My question to those who have done this on separate fiber pairs, does this buy anything other than convenience? Obviously once we start moving this way we’re going to disallow the student VLAN access to our employee VLAN and force a VPN connection if need-be. The idea behind this design is that all L2 happens on the edge which forces everything to the L3 switch at the core.
To those who have done this… Pros and Cons or pitfalls. Also from a management standpoint, how often is a change needed once it is setup?
