  - Restriction by the number of control conditions for the access list.

    - The maximum number of applicable control conditions to an interface is 6112.

    - Other functions also use control conditions. Therefore, the number of applicable control conditions may be less than 6112.

    - The remaining number of applicable control conditions decreases when the interface to which the route map is applied links up.

  - Restriction by the number of next-hop

    - The maximum number of applicable next-hop to an interface is 512.

    - The remaining number of applicable next-hop decreases when the interface to which the route map is applied and the next-hop link up.

    - The remaining number of applicable next-hop does not decrease if the same next-hop is applied to other interfaces.
