If the mn tries to send an ICMP message compaining that the packet is source routed, does it send the ICMP message by way of reversing the route used up to that point?
If so, isn't that just as bad as allowing source routing (i.e. exploits are equally possible)? If so, dropping the packet is the appropriate action over sending an ICMP message.
