hi,
i have faced the same problem: in my cas i wanted that the mac
communicate sthg to the ll
well you have to do sthg like this :

1-in tcl file :
you make $myroutingagent communicate $ll

1-in DSRAgent.cc
1-1 in commande method:
if (strcmp(argv[1], "communicate") == 0) {
			ll_ = (LL*) TclObject::lookup(argv[2]);
                        assert(ll_);
			return (TCL_OK);
		}
1-2 you have a pointer to your ll interface :)
hope helped you
