The following example shows how to configure three routers to run IS-IS as an IP routing protocol. Figure 49 illustrates the example configuration.
Router A Configuration
router isis
net 49.0001.0000.0000.000a.00
interface ethernet 0
ip router isis
interface serial 0
ip router isis
Router B Configuration
router isis
net 49.0001.0000.0000.000b.00
interface ethernet 0
ip router isis
interface ethernet 1
ip router isis
interface serial 0
ip router isis
Router C Configuration
router isis
net 49.0001.0000.0000.000c.00
interface ethernet 1
ip router isis
interface ethernet 2
ip router isis
