Usage Information
You cannot disable leaking from Level 1 to Level 2. Also, you cannot enable leaking from Level 2 to Level 1. However,
you can regulate the rate ow from one level to another using an IP Prex list. If you do not congure the IP Prex
list, all Level 1 routes are leaked.
You can nd more information in IETF RFC 2966, Domain-wide Prex Distribution with Two-Level IS-IS.
