Configure the target address as the loopback address of the remote device (in this case, the loopback address on any-router).

You must also configure the number of probes in each test, the length of time between probes, and the length of time between tests. Juniper recommends configuring between 10 and 20 probes at one-second intervals. This particular test is going to run every ten minutes

Real-Time Performance Monitoring (RPM) enables you to configure active probes to track and monitor traffic. Probes collect packets per destination and per application, including PING Internet Control Message Protocol (ICMP) packets, User Datagram Protocol and Transmission Control Protocol (UDP/TCP) packets with user-configured ports, user-configured Differentiated Services code point (DSCP) type-of-service (ToS) packets, and Hypertext Transfer Protocol (HTTP) packets. 

Probe configuration and probe results are supported by the command-line interface (CLI) and SNMP.

The following probe types are supported with DSCP marking:

ICMP echo
ICMP timestamp
HTTP get (not available for BGP RPM services)
UDP echo
TCP connection
UDP timestamp
With probes, you can monitor the following:

Minimum round-trip time
Maximum round-trip time
Average round-trip time
Standard deviation of the round-trip time
Jitter of the round-trip time—The difference between the minimum and maximum round-trip time
One-way measurements for ICMP timestamp probes include the following:

Minimum, maximum, standard deviation, and jitter measurements for egress and ingress times
Number of probes sent
Number of probe responses received
Percentage of lost probes
