The way multi-interfaces to a link work in Solairs (using something called IP Multipathing) is merely a re-interpretation of API constructs. For instance, if an application says it wants to send multicast packets out a particular interface (using IPV6_MULTICAST_IF) the stack reinterprets this as "any interface in the group of interfaces attached to the same link". The reason for this reinterpretation is because the purpose of this multipathing feature is resiliency against interface failures. If the API was different (e.g. IPV6_MULTICAST_IF was instead called IPV6_MULTICAST_ZONE with a scope zone id) the reinterpretation wouldn't be necessary I think. But the packet only goes out one interface in any case.
