681BConfiguring IS-IS route leaking
Perform this task to configure IS-IS to advertise routes from Level-2 to Level-1.
Follow these guidelines when you configure IS-IS to advertise routes from Level-2 to Level-1
• If a filtering policy is specified, only routes passing the filtering policy can be advertised into Level-1.
• If a routing policy is used, the routing policy must be specified in the import-route isis level-2 into
level-1 command to filter routes from Level-2 to Level-1. Other routing policies that are specified to
filter inbound or redistributed routes cannot filter routes advertised from Level-2 to Level-1.
