A network administratorâ€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 â€œpacket sniffer,â€ intercepting and logging traffic and providing insight into the network activities.
For this exercise, download and install Wireshark.Â
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?
