Router A, Router B, Router C, and Router D run IS-IS to implement interconnection in the
network.
The four routers belong to area 10, and the network type is broadcast (Ethernet).
Router A and Router B are Level-1-2 routers, Router C is a Level-1 router, and Router D
is a Level-2 router.
The DIS priority of RouterA is 100.
You can change the DIS priority of the interface to configure Router A as a Level-1-2 DIS.
