OpenSM calculates the unicast and multicast routes and populates the (unicast and multicast) forwarding tables. > I have queried them with ibtraceroute and ibroute, ibroute dumps the forwarding tables and ibtracert traces the path from a source to a destination so these are displaying how OpenSM has setup the fabric which is a function of the routing algorithm chosen and the physical topology (which may be dynamic). > but we need routes for the whole fabric.
