Ah, the age-old question of the DIS in an IS-IS network. Based on the database, it's clear that R1 is the DIS for Level-2. I wonder if the exam will ask us to configure the DIS priority next?

The DIS is the router with the highest System ID in the Level-2 Link State Database, and in this case, that's R1. I bet the exam question is just testing our understanding of IS-IS fundamentals. Easy peasy!

The DIS of Level-2 has to be the router with the highest System ID in the Level-2 Link State Database. Looking at the information, it seems that R1 has the highest System ID, so R1 must be the DIS.

I think the DIS of Level-2 is R1 based on the information provided. The Level-2 Link State Database shows that the LSP with the highest System ID is 0001.0100.1001.00-00, which belongs to R1.
