975.0. "IP addresses with multiple bridge domains ?" by UTOPIE::BRAUN_R () Sun Apr 27 1997 05:17

    Hi all,
    
    we would like to implement a second complete independent LAN (as in
    note 969) with 2 logical independent bridge domains. There will be
    IP and DECnet-routing between these LANs.
    For IP this means a seconds IP subnet. 
    For example, having the linecards 2-6 in this additional bridge domain,
    what about IP addresses (and default gateway,...) for sending traps,
    being reachable for ClearVISN or any other SNMP traffic,..  ?
    
    Is there a way to assign IP addresses in the new subnet for only these
    linecards (with their own subnet mask, default gateway,...).
    
    If the primary LAN fails (that's exactly why we introduce the second
    LAN), is it possible to send the traps via the second LAN ?
    Individual trap adresses possible ?
    
    
    Any help will be highly appreciated.
    
    Thanks,
    Ralph

        No, you can't assign different default gateways for different
    ports.  However, most people would do this by just defining routes for
    those subnets.
    
        IP addresses are assigned on a per port basis, and each assignment
    comes with a mask, which is not necessarily related to other IP address
    assignments/masks.
    
        Traps on the GIGAswitch/FDDI system are sent to those IP addresses
    defined in the ELAN MIB - see eauthTrapUserTable
