Using Site Manager

Enabling and Disabling Black Hole Punching

If BGP advertises aggregate routes, you can configure BGP to submit each

aggregate route to the routing table as a black hole. If IP receives a packet that

does not match any of the explicit subnet routes, the black hole route causes it to

discard the packet. (For more information about black hole routes, see “Defining a

Static Black Hole for a Supernet” on page 4-14.)

By default, BGP does not submit a black hole route to the IP routing table for an

aggregate route that it advertises to a BGP peer.

You can use the BCC or Site Manager to enable this feature. You can also

configure IP to return an ICMP destination unreachable message to the sender of a

packet to an unknown destination.
