Configuring a Probe for VRRP

VRRP supports the assigning of an ICMP probe to monitor a remote VRRP critical IP address. If an administratively configured probe name is not specified when configuring a remote critical IP address, the default VRRP ICMP probe, $vrrp_default is auto-configured to monitor the remote critical IP address. See Preset Default ICMP Probes for default ICMP probe details.

This example:

• Creates the ICMP-VRRP ICMP probe
• Sets the fail detection and pass detection intervals to 5 seconds
• Sets the internet facing IP address 20.20.20.2 on VLAN 20 as the critical-IP address for VRRP instance 1
• Sets the decrement operational priority to 10 should the interface go down
• Assigns ICMP probe ICMP-VRRP to monitor the interface
• Enables the interface
