level [1 | 2] Limits the configuration to either level 1 or level 2. If neither level 1 nor level 2 is specified, the configuration applies to both levels.



Usage Guidelines

A higher priority value is preferred over a lower priority value. The priority is encoded in level 1 or level 2 hello PDUs. This command is not valid for point-to-point interfaces. Note that a priority of 0 has no special meaning other than the fact that it is the lowest priority. A router with a priority of 0 can still become the DIS.
