6.18.1 Example for Configuring Basic IS-IS Functions
Networking Requirements
As shown in Figure 6-3:
l SwitchA, SwitchB, SwitchC, and SwitchD belong to the same domain. The IS-IS routing
protocol runs on these four Switches to ensure connectivity on an IP network.
l The areas IDs of SwitchA, SwitchB, and SwitchC are all 10, and the area ID of SwitchD
is 20.
l SwitchA and SwitchB are Level-1 Switches. SwitchC is the Level-1-2 Switch. SwitchD is
the Level-2 Switch.
