Explanation:
R3
* Understanding the LSDB and Level-2 DIS Election in IS-IS :
* In IS-IS, the Designated Intermediate System (DIS) is elected for both Level-1 and Level-2 on broadcast networks to manage the link-state database (LSDB) and reduce the number of LSAs exchanged.
* The election of the DIS is based on the highest priority . If the priority is the same, the router with the highest System ID becomes the DIS.
* HCIP-Datacom-Core Technology Training Material (IS-IS DIS Election) .
Analyzing the LSDB :
From the LSDB of R1 , the Level-2 link-state database includes the following entries:
LSPID 0100.0000.3003.00-00 : This is R3, and it is present in the Level-2 LSDB with the sequence number and checksum details.
Other routers (R1, R2, R4) are present but do not have the characteristics of the Level-2 DIS in this topology.
Based on the System IDs, R3 (0100.0000.3003) has the highest System ID, making it the Level-2 DIS .
Conclusion :
The Level-2 DIS on the network is R3 , based on the election rules and the LSDB information shown in the figure.
