The following configuration enables IS-IS on Ethernet interface 1 and serial interface 0 and advertises
the IP addresses of Ethernet interface 0 in its link-state protocol data units (PDUs):
Switch(config-if)# router isis Finance
Switch(config-router)# passive-interface Ethernet 0
Switch(config-router)# interface Ethernet 1
Switch(config-router)# ip router isis Finance
Switch(config-router)# interface serial 0
Switch(config-router)# ip router isis Finance
Switch(config-router)#
The following example sets all interfaces as passive, then activates Ethernet interface 0:
Switch(config-if)# router ospf 100
Switch(config-router)# passive-interface default
Switch(config-router)# no passive-interface ethernet0
Switch(config-router)# network 10.108.0.1 0.0.0.255 area 0
Switch(config-router)#
The following configuration sets the Ethernet ports 3 through 4 on module 0 and GigabitEthernet ports
4 through 7 on module 1 as passive:
Switch(config-if)# router ospf 100
Switch(config-router)# passive-interface range ethernet0/3-4,gigabitethernet1/4-7
Switch(config-router)#
