An attacker attaches a rogue router in a network. He wants to redirect traffic to a LAN attached to his router as
part of a man-in-the-middle attack. What measure on behalf of the legitimate admin can mitigate this attack?

A.
Only using OSPFv3 will mitigate this risk.

B.
Make sure that legitimate network routers are configured to run routing protocols with authentication.

C.
Redirection of the traffic cannot happen unless the admin allows it explicitly.

D.
Disable all routing protocols and only use static routes.
