Description

The following predefined applications are similar and return the same content:

application junos-icmp-all {
term t1 protocol icmp;
}
application junos-ping {
    term t1 protocol 1;
}

This article explains the difference between these two applications.

Solution

Functionally, j unos-ping and j unos-icmp-all are the same. The target protocol for both applications is all types of ICMP, as shown above.

These two applications are inherited for configuration compatibility.

  • junos-icmp-all  was used by J-Series and MX/T-Series as part of Junos OS.

  • junos-ping came from Netscreen as part of Junos-ES OS.

When the two operating systems merged, both applications remained to preserve configuration compatibility.
