Just because your machine is not forwarding packets does not mean that it does not need routes. For instance, any machine that wishes to contact the outside world needs a default route. I think it simply is telling you that a temp route that was added due to an ICMP redirect from another machine has expired and has therefore been removed. You seem to be getting debug messages though: route.c: printk(KERN_DEBUG "ip_rt_advice: redirect to %d.%d.%d.%d/%02x dropped\n", NIPQUAD(rt->rt_dst), rt->key.tos);
