Blackhole Routes

  • From: Abhishek Verma

Hi,

There are ways to add static routes that can be blackholed. I can
understand the utility of such routes if those are installed in my
forwarding table. What bewilders me is why would anyone want to
advertise "blackhole" routes using say, BGP?

Is it only to prevent some sort of DoS attacks or are there other uses
also of advertising black hole routes?

Thanks,
Abhishek
