MikroTik RouterOS V2.4 Traceroute

Document revision 11-December-2001
This document applies to MikroTik RouterOS V2.4

Overview

Traceroute is a TCP/IP protocol-based utility, which allows the user to determine how packets are being routed to a particular host. Traceroute works by increasing the time-to-live value of packets and seeing how far they get until they reach the given destination; thus, a lengthening trail of hosts passed through is built up.

Topics covered in this manual:

Installation

The Traceroute feature is included in the 'system' package. No installation is needed for this feature

Hardware Resource Usage

There is no significant resource usage.

Traceroute Description

Traceroute shows the number of hops to the given host address of every passed gateway. Traceroute utility sends packets three times to each passed gateway so it shows three timeout values for each gateway in ms. The Traceroute session may be stopped when the Ctrl + C is pressed.

[MikroTik] tool> traceroute ?
Trace route to host by increasing Time To Live value in sent packets and waiting for "TTL expired" messages from routers.

  <address>  IP address of host
       port  UDP port number
   protocol  Protocol of sent packets
       size  Packet size
    timeout  Response wait timeout
        tos  Type of service

Descriptions of arguments:

address - IP address of the host you are tracing route to.
port - Port number. Values are in range 0-65535.
protocol - Type of protocol to use (UDP or ICMP). If one fails (for example, it is blocked by a firewall) try the other.
size - (optional) Packet size in bytes (28..1428, default 64).
timeout - (optional) Response waiting timeout, i.e. delay between messages. Can be 1..5s, default 1s.
tos - Type Of Service – parameter of IP packet. Can be 0..255, default 0.
