Description

Specify the probes for split-brain detection.

Options

bfd-liveliness—

BFD-based probes to prevent split-brain scenarios.

dest-ip ip-address—

destination IP address to send the probe requests. Use this option for ICMP based probes for split-brain detection.

  • routing-instance name—Routing instance used by the probe requests.
  • src-ip ip-address—Source IP address to send the probe requests.
Note:

ICMP-based split-brain probing and BFD-based split-brain probing are mutually exclusive.

minimal-interval milliseconds—

(Optional) Time period between the probes sent to the destination IP address. You can configure 1000 milliseconds for minimal interval activeness probes. (supported in default gateway [switching] and hybrid deployments).

multiplier number—

(Optional) Time period, after which the backup node transitions to the active state, if the backup node fails to receive response to the activeness-probes from the peer node. (supported in default gateway [switching] and hybrid deployments).

  • Range: 2 through 15

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
