Use this command to configure a route-map probe session to monitor the specified next hop address.
| ip-address | Specifies the next hop IPv4 or IPv6 address for this probe session to monitor. |
| probe-name name | default | Specifies the name of an administratively created ICMP probe to use for this session, or the $pbr_default default ICMP probe when the default keyword is specified. |
None.
Global configuration.
The route-map probe feature supports ICMP probes. When assigning an ICMP probe to monitor a next hop IP address, the port is auto-set to port 0 of the specified IP address. The probe is not assigned to a specific route-map. If a next hop IP address is declared down, it is removed from the next hop selection process for all route-maps specifying this address as a next hop, until it is declared up again.
The $pbr_default ICMP probe can not be specified directly. Use the default keyword to specify the $pbr_default ICMP probe.
Note
On the S- and K-Series, next hop probes over layer 3 tunnels are not currently supported. The remote address will be declared down regardless of its state and the layer 3 tunnel will be taken down. Use tunnel probe to monitor a layer 3 tunnel remote address.The “no” form of this command removes the specified next hop IP address probe session.
This example shows how to configure probe ICMP-PBR and assign it to monitor the next hop IP addresses 125.50.25.1 and 2000::1301:0:21f:45ff:fe4d:8722 (references to SLB and TWCB are S-Series only):
