    Hello Sun Managers!,

    I have a question regarding IP Multipathing:

    I'm working on a Sun system that has at least 4 NICS. I want to setup 2
    Multipathing groups each with 1 VIP and two physical interfaces. In this
    case both primary IP addresses (for example a, b) have to be on different
    subnets. The machine will not be configured as a router.

    It's my understanding that IPMP expects an ICMP response from the
    defaultrouter in order to work. How should we configure the
    defaultrouter(s)? We don't want to implement in.routed/in.rdisk. Is there a
    requirement to specify the defaultroute per interface?

    Subnet A (192.168.10.x)
    (eri0) a1--
               --a (failover virtual interface eri0:1 or qfe0:1)
    (qfe0) a2--

    Subnet B (192.168.20.x)
    (eri1) b1--
               --b (failover virtual interface eri1:1 or qfe1:1)
    (qfe1) b2--

    Any help on this would be great!
