To configure the IS level and circuit level: Step 1. Enter system view. 2. Enter IS-IS view. 3. Specify the IS level. 4. Return to system view. 5. Enter interface view. 6. Specify the circuit level. Command Remarks system-view N/A isis [ process-id ] [ vpn-instance vpn-instance-name ] N/A is-level { level-1 | level-1-2 | level-2 } By default, the IS level is Level-1-2. quit N/A interface interface-type interface-number N/A isis circuit-level [ level-1 | level-1-2 | level-2 ] By default, an interface can establish either the Level-1 or Level-2 adjacency. Configuring P2P network type for an interface Perform this task only for a broadcast network that has up to two attached routers. Interfaces with different network types operate differently. For example, broadcast interfaces on a network must elect the DIS and flood CSNP packets to synchronize the LSDBs, but P2P interfaces on a network do not need to elect the DIS, and have a different LSDB synchronization mechanism. If only two routers exist on a broadcast network, configure the network type of attached interfaces as P2P to avoid DIS election and CSNP flooding, saving network bandwidth and speeding up network convergence. To configure P2P network type for an interface: Step 1. Enter system view. 2. Enter interface view. Command system-view interface interface-type interface-number 3. Configure P2P network type for an interface. isis circuit-type p2p Remarks N/A N/A By default, the network type of an interface depends on the physical media. The network type of a VLAN interface is broadcast. Configuring IS-IS route control Configuration prerequisites Before the configuration, complete the following tasks: • Configure IP addresses for interfaces to ensure IP connectivity between neighboring nodes. • Enable IS-IS. 117
