MTR on JUNOS
From JuniperClue
Since JUNOS 8.0 there is a new option which allows to run traceroute in a 'MTR-like' mode:
user@juniper> traceroute monitor $DESTINATION
where $DESTINATION is an IP or domain-name of the target host.

You can do a more intensive version of this through the shell. Requires root access
user@juniper> start shell % su Password: root@CR1% mtr -i 0.02 4.2.2.2
