Manually Applied Default ICMP Probes

Manually applied default ICMP probes are treated the same as an administratively created ICMP probe and are provided for your convenience, should the preset parameter values meet your needs.

The Policy Based Routing (PBR) default ICMP probe must be manually applied. Use the route-map probe command in global configuration mode to apply the PBR default ICMP probe ($pbr_default) to monitor the specified next hop IP address. When configuring a default ICMP probe, the probe cannot be specified by name. Use the default keyword when configuring the default route-map probe.

The following example configures the default $pbr_default ICMP probe to monitor IP address 125.50.25.1:

System(su-config)->route-map probe 125.50.25.1 probe-name default

The VRRP default ICMP probe is used to monitor remote critical IP addresses. When configuring a default ICMP probe, the probe cannot be specified by name. The VRRP default probe is configured when the remote keyword is specified. Use the vrrp critical-ip command in interface configuration mode, specifying the remote keyword, to apply the VRRP default probe to a critical IP interface.

This example 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 100 should the interface go down, and assigns the VRRP default probe $vrrp_default to monitor the interface:

System(rw)->configure
System(rw-config)->interface vlan 20
System(rw-config-intf-vlan.0.20)->vrrp critical-ip 1 20.20.20.2 100 remote probe-name $vrrp_default
System(rw-config-intf-vlan.0.20)->no shutdown
System(rw-config-intf-vlan.0.20)->
