Network requirements
As shown in Figure 64, S witch A, B, C, and D reside in IS-IS area 10 on a broadcast network (Ethernet).
Switch A and Switch B are Level-1-2 switches, Switch C is a Level-1 switch, and Switch D is a Level-2 switch.
Change the DIS priority of Switch A to make it elected as the Level-1-2 DIS router.

By using the default DIS priority, Switch C is the Level-1 DIS, and Switch D is the Level-2 DIS. The
pseudonodes of Level-1 and Level-2 are 0000.0000.0003.01 and 0000.0000.0004.01.
3. Configure the DIS priority of Switch A:
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] isis dis-priority 100
[SwitchA-Vlan-interface100] quit
# Display IS-IS neighbors of Switch A.

They use IS-IS to interconnect. Switch A and Switch B are Level-1 routers, Switch D is a Level-2 router, and Switch C is a Level-1-2 router. Redistribute RIP routes into IS-IS on Switch D.
