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 the IS-IS routing table of SwitchA.
3. Configure route convergence on SwitchB.
Data Preparation
To complete the configuration, you need the following data:
l VLAN ID of each interface, as shown in Figure 6-4
l IP address of each VLANIF interface, as shown in Figure 6-4
l System ID, level, and area ID of each Switch
– SwitchA: The system ID is 0000.0000.0001; the area ID is 20; the level is Level-2.
