• For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.Distribute RoutesAnother 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 Dell Networking OS doesnot 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 toAccess Control Lists (ACLs).Applying IPv4 RoutesTo 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 ADDRESS-FAMILY IPV6 mode, shownlater.• Apply a configured prefix list to all incoming IPv4 IS-IS routes.ROUTER ISIS modedistribute-list prefix-list-name in [interface]Enter the type of interface and the interface information:• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port[/subport] information.• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.• For a Loopback interface, enter the keyword loopback then a number from 0 to 16383.• For a port channel interface, enter the keywords port-channel then a number.• For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.• Apply a configured prefix list to all outgoing IPv4 IS-IS routes.ROUTER ISIS modedistribute-list prefix-list-name out [bgp as-number | connected | ospf process-id | rip |static]You can configure one of the optional parameters:• connected: for directly connected routes.• ospf process-id: for OSPF routes only.• rip: for RIP routes only.• static: for user-configured routes.• bgp: for BGP routes only.• Deny RTM download for pre-existing redistributed IPv4 routes.ROUTER ISIS modedistribute-list redistributed-override inApplying IPv6 RoutesTo apply prefix lists to incoming or outgoing IPv6 routes, use the following commands.NOTE: These commands apply to IPv6 IS-IS only.
