On a P2P link, Level-1 and Level-2 hello packets are advertised in P2P hellopackets, so you need not specify Level-1 or Level-2.Configuring a DIS priority for an interfaceOn an IS-IS broadcast network, you must elect a router as the DIS at a routing level. You canspecify a DIS priority at a level for an interface. The greater the interface’s priority, the morelikely it becomes the DIS. If multiple routers in the broadcast network have the same highest DISpriority, the router with the highest MAC address becomes the DIS.To do… Use the command… RemarksStep 1 Enter system view system-view ––Step 2 Enter interface view interface interface-type interface-number ––Step 3 Specify a DIS priorityfor the interfaceisis dis-priority value [ level-1 | level-2 ]Optional64 by defaultDisabling an interface from sending or receiving IS-ISpacketsAfter being disabled from sending or receiving hello packets, an interface cannot form anyneighbor relationship, but can advertise directly connected networks in LSPs through otherinterfaces. By doing so, you can save bandwidth and CPU resources while ensuring other routersknow networks directly connected to the interface.To do… Use the command… Remarks
