In an OSPF packet capture, a Type 2 LSA indicates that the packet originated from which type of router?

A Type 2 LSA, also known as a network LSA, is generated by the designated router (DR) in an OSPF network segment that operates in broadcast or non-broadcast multi-access (NBMA) modes. The purpose of this LSA is to represent the state of the multi-access network and to provide information about the routers attached to it. When the DR creates this LSA, it includes information about the routers that are directly connected to the network, which allows other OSPF routers to learn about the topology of that segment.

The designated router takes on this role to minimize the number of LSA updates that need to be exchanged within the network; instead of each router flooding information about its neighbors, the DR consolidates this information and disseminates it, effectively reducing the amount of routing overhead.

Given this context, recognizing that a Type 2 LSA specifically originates from the designated router clarifies why this is the correct answer regarding the question about where the packet originated from.
