Controlling Routing Updates To control the source of IS-IS route information, use the following command. • Disable a specific interface from sending or receiving IS-IS routing information. ROUTER ISIS mode passive-interface interface - For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet then the slot/port information. - For the Loopback interface on the RPM, enter the keyword loopback then a number from 0 to 16383. - For a port channel, enter the keywords port-channel then a number. - For a SONET interface, enter the keyword sonet then the slot/port information. - For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/ port information. - For a VLAN, enter the keyword vlan then a number from 1 to 4094. Distribute Routes Another method of controlling routing information is to filter the information through a prefix list. Prefix lists are applied to incoming or outgoing routes and routes must meet the conditions of the prefix lists or the system does not install the route in the routing table. The prefix lists are globally applied on all interfaces running IS-IS. Configure the prefix list in PREFIX LIST mode prior to assigning it to the IS-IS process. For configuration information on prefix lists, refer to Access Control Lists (ACLs). Applying IPv4 Routes To apply prefix lists to incoming or outgoing IPv4 routes, use the following commands. NOTE: These commands apply to IPv4 IS-IS only. To apply prefix lists to IPv6 routes, use ADDRESSFAMILY IPV6 mode, shown later. • Apply a configured prefix list to all incoming IPv4 IS-IS routes. ROUTER ISIS mode distribute-list prefix-list-name in [interface] - Enter the type of interface and slot/port information: - For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet then the slot/port information. - For the Loopback interface on the RPM, enter the keyword loopback then a number from 0 to 16383. - For a port channel, enter the keywords port-channel then a number. - For a SONET interface, enter the keyword sonet then the slot/port information. - For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information. - For a VLAN, enter the keyword vlan then a number from 1 to 4094. • Apply a configured prefix list to all outgoing IPv4 IS-IS routes.
