Remotely Triggered Black Hole

Remotely Triggered Black Hole (RTBH) filtering is a self-managed feature that enables you to block unnecessary traffic before it enters Equinix Internet Exchange (IX) protected network. RTBH protects you from Distributed Denial of Service (DDoS) attacks.

RTBH Services

  • Equinix provides Black Hole Host with IP address .240 (in APAC), or .253 (in AMER and EMEA) on the IX subnet with mac address 0050.56bb.bbbb.
  • All unicast traffic towards the Black Hole Host is denied at customer facing ports (by mac-address ACL).

For more information on the RTBH Host and other supported BGP communities, see RTBH Host information.


Distributed Denial of Service

Distributed Denial of Service (DDoS) attack causes disruption of services due to unnecessary inbound traffic in your port. RTBH filtering can help to free the port utilization from this unnecessary traffic.

To free the port utilization, the Equinix MLPE route server inserts a BGP route into the network that forces the routers to stop all traffic to the Black Hole Host with predefined IP and MAC addresses.

Mitigation Stages

To mitigate the risk of DDoS attacks, RTBH involves the following stages:
