Is this the code?
        int dst = Address::instance().get_nodeaddr(hdr->dst());
        tcl.evalf("%s tunnel-exit %d", name_, dst);
        int te = atoi(tcl.result());
the second line above is an upcall to the tcl interpreter resulting in an
instproc 'tunnel-exit' being called with the argument 'dst'.
