    Number of vlan/interfaces on Juniper M7i

    Hi,

    We are currently setting up a network for a large building (700 clients) and are considering using the Juniper M7i router as a core router for this network.

    Have anyone experience in loading 700 interfaces onto this router on a gigabit interface with vlans? I know the number of vlans is within the spesifications of the product - but have anyone tested it or have any qualified quesses if it will work?

    The setup is simple


    gigabit line --> juniper m7i --> vlan each end client with cheap edge switches

    --------

    We have already chosen the technical plattform, including the use of /30 networks on all of the clients and are going for this solution. The question now is - will the router be able to handle this amount of interfaces/vlans on 1gbps?

    You'll need "cheap edge switches" that can also handle 700 vlans and trunking protocols. Don't know of many cheap ones ;-)

    I know - some local dealer here have sold us some cheap equipment that can do that - but can the juniper do the trick?

    This type of topology seems pretty ill advised. Your Juniper M5 router will be a single point of failure, and configuring downstream switches for all those vlans will be nightmarish. However, gigE pics have a limit of 1024 VLANs per port so you could technically do this. My hunch, though, is that if you have to ask this question - you really should get some expert advice on your network topology, infrastructure, etc.
