IS-IS can be enabled for a specified interface for a device. Several commands can then be accessed that allow the configuration of IS-IS on the specified interface. This task enables IS-IS routing for an interface Ethernet.
device# configure terminal
device(config)# interface ethernet 1/2
device(conf-if-eth-1/2)# ipv6 address 2001:db8:12d:1300::/64 eui-64
device(conf-if-eth-1/2)# ipv6 router isis
The following example enables IS-IS routing for an interface Ethernet and assigns an IPv6 address to the interface.
device# configure terminal device(config)# interface ethernet 1/2 device(conf-if-eth-1/2)# ipv6 address 2001:db8:12d:1300::/64 eui-64 device(conf-if-eth-1/2)# ipv6 router isis
