IP Reachability Detection

The IP Reachability Detection feature uses the Bidirectional Forwarding Detection (BFD) protocol or the ICMP ping to detect whether remote IP addresses are reachable.

Introducing Bidirectional Forwarding Detection (BFD)

Starting from R81.10.07, Quantum Spark supports Bidirectional Forwarding Detection (BFD).

For more information, see RFC 5880 and RFC 5881.

In a Cluster of Quantum Spark Appliances:

  • Only the Active member sends and accepts BFD packets.

  • The Standby member does not send or accept BFD packets. It treats the Active cluster member as reachable.

To configure in BGP

In the WebUI

  1. In the BGP page, click to edit a group and then an individual peer.

    The Edit Peer window opens.

  2. For the IP reachability detection field, select an option from the pull-down menu:

    • Off

    • Singlehop BFD - When you select this option, the Check control plane failure checkbox appears.

    • Multihop BFD - If you select this option, you must enter the IP reachability local address and you can select the Check control plane failure box.

  3. Click Apply.
