001 Up Down 1497 L1/L2 No/Yes
By using the default DIS priority, Router C is the Level-1 DIS, and Router D is the Level-2 DIS. The
pseudonodes of Level-1 and Level-2 are 0000.0000.0003.01 and 0000.0000.0004.01
respectively.
3. Configure the DIS priority of Router A:
[RouterA] interface GigabitEthernet 1/1/1
[RouterA-GigabitEthernet1/1/1] isis dis-priority 100
# Display information about IS-IS neighbors of Router A.
[RouterA] display isis peer
