Huawei S1720 Series Configuration Guide

l SwitchA, SwitchB, SwitchC, and SwitchD are interconnected by running the IS-IS
protocol.
l SwitchA, SwitchB, SwitchC, and SwitchD belong to Area 10.
l SwitchA and SwitchB are Level-1-2 switches. SwitchC is the Level-1 Switch. SwitchD is
the Level-2 Switch.
l It is required to change the DIS priority of the interface to configure SwitchA to a Level-1-2
DIS.

Configuration Roadmap
The configuration roadmap is as follows:
1. Enable basic IS-IS functions on each Switch so that the Switches can be interconnected.
2. Check information about the IS-IS interface on each Switch with the default priority.
3. Configure the DIS priority on the Switch.
Data Preparation
To complete the configuration, you need the following data:
l VLAN ID of each interface, as shown in Figure 6-5
l IP address of each VLANIF interface, as shown in Figure 6-5
l System ID, level, and area ID of each Switch
– SwitchA: The system ID is 0000.0000.0001; the area ID is 10; the DIS priority is 100;
the level is Level-1.
