to verify the effect of the configuration. Execute the debugging command in user
view to debug the IS-IS module.
Integrated IS-IS
Configuration Example
As is shown in Figure 11, Switches A, B, C and D belong to the same autonomous
system. The IS-IS routing protocol is run in these four switches to implement route
interconnection. In network design, switches A, B, C and D belong to the same
area.
This example shows only the IS-IS configuration. You must also configure IP
addresses on the vlan interface of each switch.
