Traceroute On JunOS

JunOS has been built on one of the most famous Unix based operating systems “FreeBSD”, so it makes sense if JunOS inherits some of the BSD tools, Yes JunOS Ping/Traceroute implementation works exactly like BSD.

Traceroute used to discover the path taken by packets to reach specific destination across an IP network.

When the command is executed, three UDP packets are generated. Each packet uses the supplied end-host information as the destination IP address. The outgoing interface of the router is used as the source IP address.

The time-to-live (TTL) value is set to 1 and the destination UDP port is set to 33434. These packets are then sent out into the network.
