○ 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 IPv6 IS-IS routes.
ROUTER ISIS-AF IPV6 mode
distribute-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 IPv6 routes.

Redistributing IPv4 Routes
In addition to filtering routes, you can add routes from other routing instances or protocols to the IS-IS process. With the
redistribute command syntax, you can include BGP, OSPF, RIP, static, or directly connected routes in the IS-IS process.
NOTE: Do not route iBGP routes to IS-IS unless there are route-maps associated with the IS-IS redistribution.
To add routes from other routing instances or protocols, 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,
shown later.
● Include BGP, directly connected, RIP, or user-configured (static) routes in IS-IS.
ROUTER ISIS mode
redistribute {bgp as-number | connected | rip | static} [level-1 level-1-2 | level-2]
[metric metric-value] [metric-type {external | internal}] [route-map map-name]
Configure the following parameters:
○ level-1, level-1-2, or level-2: assign all redistributed routes to a level. The default is level-2.
○
metric-value the range is from 0 to 16777215. The default is 0.
○ metric-type: choose either external or internal. The default is internal.
○ map-name: enter the name of a configured route map.
● Include specific OSPF routes in IS-IS.
ROUTER ISIS mode
redistribute ospf process-id [level-1| level-1-2 | level-2] [metric value] [match
external {1 | 2} | match internal] [metric-type {external | internal}] [route-map map-
name]
Configure the following parameters:
○ process-id the range is from 1 to 65535.
○ level-1, level-1-2, or level-2: assign all redistributed routes to a level. The default is level-2.
○ metric value the range is from 0 to 16777215. The default is 0.
○ match external the range is from 1 or 2.
○ match internal
