How do you traceroute a router?

How do I run a traceroute from one IP address to another?

How does traceroute get each router to respond to it?

A traceroute works by sending Internet Control Message Protocol (ICMP) packets, and every router involved in transferring the data gets these packets. The ICMP packets provide information about whether the routers used in the transmission are able to effectively transfer the data.

What ports do traceroute use?

Sets the base UDP port number used in probes. The default is 33434. The traceroute command depends on an open UDP port range of base to base + nhops – 1 at the destination host. If a UDP port is not available, this option can be used to pick an unused port range.

How do you read a traceroute output?

How to read a Traceroute

1. Hop Number – This is the first column and is simply the number of the hop along the route.
2. RTT Columns – The next three columns display the round trip time (RTT) for your packet to reach that point and return to your computer.
3. Domain/IP column – The last column has the IP address of the router.

How to test extended Ping and extended traceroute?

This way, only the connectivity between the serial 0 interface of Router A (172.31.20.1) and the Ethernet interface of Router B (192.168.40.1) is tested. In order to test the connectivity between Router A Ethernet 0 (172.16.23.2) and Router B Ethernet 0 (192.168.40.1), use the extended ping command.

What is the difference between record and traceroute?

The difference between using the Record option of this command and using the traceroute command is that, the Record option of this command not only informs you of the hops that the echo request (ping) went through to get to the destination, but it also informs you of the hops it visited on the return path.
