Configuring Route Redistribution

You can redistribute routes into IS-IS for route types and protocols: BGP, connected, OSPF, RIP, Static and blackhole. You can also redistribute IS-IS Level 2 routes into Level 1.

A route map can be applied to a redistribution configuration to filter the routes that will be redistributed for the specified route type or protocol. You can also specify a protocol metric value for BGP, connected, RIP, or static redistribution routes.

You must be in IS-IS IPv6 unicast address family configuration mode to configure redistribution on an IPv6 IS-IS intermediate system instance. See Configuring the IPv6 Unicast Address Family for details on entering IS-IS IPv6 unicast address family configuration mode.

If you do not specify a distribute list when redistributing IS-IS level 2 routes into IS-IS level 1, all layer 2 addresses are redistributed into layer 1.

Use the redistribute command in IS-IS configuration or IS-IS IPv6 unicast address family configuration mode to specify the protocol or route type to redistribute into IS-IS.
