You can configure IS-IS to exchange CLNS routes within a CLNS island. To export BGP routes into IS-IS, you must configure and apply an export policy. For more information about policies, see Configuring Routing Policies.
If you have a pure CLNS island—an island that does not contain any IP devices—you must disable IPv4 and IPv6 routing.
To configure IS-IS for CLNS:
