I bet the engineer's next recommendation is to just unplug the router and hope the problem goes away. Problem solved!

B) That might help, but I think the engineer should also consider using subinterface command no ip directed-broadcast

Option A seems promising, but I'm not sure it's the complete solution. Verifying reverse-path forwarding is a good start, but we might need to do more.

Haha, Option D is a classic! Logging everything at level 6 is definitely not the way to go. Way too much data!

I'm not sure Option B is relevant here. Enabling TCP keepalives doesn't seem to address the ICMP flooding issue.

Option C looks like the right choice here. Disabling IP directed broadcasts on the subinterface should help mitigate the attack.
