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.

[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.
