2658.0. "Routing multiple nets, brouter, switch questions" by PTOJJD::DANZAK (Pittsburgher �) Mon Aug 21 1995 18:28

    Folks..
    
    I have multiple buildings which will be coming into a DEChub 900 with
    class c networks.  If I have a DECbrouter 90 and DECswitch 900EF, can I
    bring multiple subnets into the EF (via  a Portswitch 900FP) and then
    use the DECbrouter 90's one Ethernet port to basically subnet route
    back to the same Ethernet for IP stuff.  
    
    OR....do I need to use the EF with routing code to do that.....?
    
    AND...can a 900EF route two DIFFERENT subnets to one port with 1.) IP
    routing code and 2.) FULL routing code.
    
    AND.....which is likely to offer better performance....?
    
    My guess is that ALL combos of the above would/should work and that the
    best performance may be routing via the DECbrouter 90.
    
    ANy thoughts?
    
    Thanks,

    The DECbrouter 90 can provide routing between different subnets on the
    same lan.  We have done this in the past because it is the only hub based 
    router we really have(waiting for routing code).
    
    Since the DECbrouter 90 only has the one ethernet interface all traffic
    from the 900EF will have to get dumped on and off the thinwire.  That
    might be a bottle neck.
    
    Might check the routing software notes file for your other question.

    You might want to cross-post the base note there Jon, to further
    supplement any answers you might get here.
