This lab involves analysis of a packet capture (pcap) file (MPLS_encapsulation.cap) using the Wireshark network analysis tool. This pcap file is available on Blackboard as an attachment to the project assignment. Open the file in Wireshark and use it to determine answers to the questions below. Turn-in Requirements: To complete the assignment, upload a Word (.docx) or Adobe (.pdf) file with answers to the numbered questions as your submission to this assignment in Blackboard.

(10 pts) Recall the discussion of multiprotocol label switching (MPLS) from the lecture slides. Highlight the first packet and examine the Packet Details pane. In what layer of the OSI model does the MPLS data reside? Explain your answer. 2. (10 pts) Assume that the first packet is being forwarded by an entry point router of an MPLS-based carrier network. Which piece of information, displayed in the Packet Details pane, is directly responsible for determining how the packet will be routed through the carrier network? 3. (10 pts) A time-to-live (TTL) value is set as part of various routing protocols to ensure that a misrouted packet does not bounce around the network indefinitely. As a packet is processed at each router (i.e. - at each "hop"), the TTL value is reduced by one. If/when the TTL value reaches zero, the packet is dropped. How many "hops" between routers could the first packet make before it would be dropped?
