level-2: Generates a default route for Level-2.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63

Usage guidelines
If no level is specified, this command generates a Level-2 default route.
You can use a routing policy to specify a level for the default route. The default route can be generated
only when the routing policy is matched by a route entry in the routing table. The apply isis level-1
command in routing policy view specifies Level-1. The apply isis level-2 command in routing policy view
specifies Level-2. The apply isis level-1-2 command in routing policy view specifies both Level-1 and
Level-2.
