I would think this is only true because loopbacks don't send ICMP unreachables,
thus a performance improvement. Adding "no ip unreachables" to null0 probably
makes them equivalent.

// Typically, I have seen black hole routes configured as:
//
// ip route 10.0.0.0 255.0.0.0 null0
//
// Recently, I read somewhere that if you point them to a loopback you will get
// better performance.
//
// ip route 10.0.0.0 255.0.0.0 lo0
//
// Unfortunately, I have lost the reference. Does anyone agree with this, and
// if so, can you explain the details as to why?
//
// Thanks for any information!
