Usage guidelines
You can specify a routing policy in the import-route isis level-2 into level-1 command to filter routes from
Level-2 to Level-1. Other routing policies specified for route reception and redistribution does not affect the
route leaking.
If a filter policy is configured, only routes passing it can be advertised into the Level-1 area.
If no topology is specified, the Level-2 routes of the base topology are advertised to Level-1.
