A network administrator’s job is to understand and troubleshoot network protocols.
Administrators commonly use a tool called Wireshark, which enables you to analyze protocols and acts as a “packet sniffer,” intercepting and logging traffic and providing insight into the network activities.
For this exercise, download and install Wireshark.
Open the routing.pcap file in Wireshark and respond to the following questions:
- Compare and contrast the RIPv1, RIPv2, OSPF, and EIGRP routing protocols.
- Which routing protocols use multicast and which use broadcast?
- What are the multicast addresses used by the routing protocols?
- Is TCP or UDP used?
- What is the port number?
- Are you able to find the autonomous system number for EIGRP in the packet details? How did you locate it?
- How do you think parsing through capture files will help you better understand routing protocols and networking?
